# Summarytools in R Markdown Documents

#### Dominic Comtois

# 1. Introduction

This document mainly contains examples showing how best to use summarytools in R Markdown documents. For a more in-depth view of the package’s features, please see `vignette("introduction", "summarytools")` - the online version can be found here.

## 1.1 Methods vs Styles

Every time we display summarytools objects with `print()`, `view()`, or `stview()`, we pick – explicitly or not – one of several display methods. Possible display methods are: pander, render, viewer, and browser. It is one of the parameters for `print.summarytools()` and `view()` (alias: `stview()`).

Since methods viewer and browser are mostly meant for interactive work and rely on the same underlying code as render, we will assume for the purpose of this document that there are really only two methods: pander and render.

### Only the pander Method Uses Styles

The pander method is used by default when results are automatically printed to the console, or when we use `print()` without an explicit `method` argument.

The style parameter is communicated to pander (see `?pander::pander` or visit its GitHub page to learn more on this very useful package).

| When we use any of the viewer, browser, or render methods, the package uses htmltools to generate results; any specified styles are thus ignored.

### summarytools styles are pander styles

Available styles are the ones supported by pander:

- simple (default, used mainly in R console)
- rmarkdown (used by all core functions except `dfSummary()`)
- grid (mainly used with `dfSummary()`)
- multiline (can be used with `dfSummary()` if you use ascii graphs only)
- jira (more recent addition, not thoroughly tested)

## 1.2 General Guidelines

Always set results=‘asis’ either explicitly on a chunk-by-chunk basis or by including `opts_chunk$set(results = 'asis')` in your setup chunk.

Also, don’t forget to specify `plain.ascii = FALSE` in all function calls using the pander method. It is advised to set this option, as well as the `style` option in the setup chunk:

    st_options(plain.ascii = FALSE, style = "rmarkdown")

| If you get repeated, unhelpful warnings, use chunk options `message = FALSE` and/or `warning = FALSE`. Another option is to use the argument `silent = TRUE` to the `print()` method or `view()` / `stview()` functions. See `?st_options` to set this globally for individual functions.

The following table indicates which method / style is better suited for each summarytools function in the context of R Markdown documents:

Function | render method | pander method | pander style
--- | --- | --- | ---
freq() | ✓ | ✓ | rmarkdown
ctable() | ✓ | Sub-optimal | rmarkdown
descr() | ✓ | ✓ | rmarkdown
dfSummary() | ✓ | ✓ | grid

Recommended Style When Using pander method

For `freq()`, `descr()`, and `ctable()`, rmarkdown style is recommended. For `dfSummary()`, grid is recommended. Note that multiline can also be used, but only ascii graphs will be displayed.

Starting with `freq()`, we’ll now review the recommended methods and styles to get satisfying results in R Markdown documents.

# 2. Using freq() in R Markdown

`freq()` is best used with method “pander” (default), `style = "rmarkdown"`; html rendering is also possible.

## 2.1 Pander Style for freq()

With `method = "pander"`, `style = "rmarkdown"` is the easy winner. Since “pander” is the default method, you can usually omit the call to `print()`. But to make things as clear as possible, we’ll include it here.

    print(freq(tobacco$gender,
               plain.ascii = FALSE,
               style = "rmarkdown"),
          method = "pander")

## 2.2 HTML Rendering for freq()

There are rarely any problems when using the render method to display `freq()` results.

    print(freq(tobacco$gender), method = "render")

If you find the table is too large, you can use `table.classes = "st-small"`:

    print(descr(tobacco), method = "render", table.classes = "st-small")

# 3. Using ctable() in R Markdown

## 3.1 Rmarkdown Style for ctable()

Tables with multi-row headings are not fully supported in markdown (yet), but the result is close to acceptable. This, however, is not true for all themes. That is why the rendering method is preferred.

    ctable(tobacco$gender,
           tobacco$smoker,
           plain.ascii = FALSE,
           style = "rmarkdown")

### Cross-Tabulation, Row Proportions

Total |  | 298 (29.8%) | 702 (70.2%) | 1000 (100.0%)

## 3.2 HTML Rendering for ctable()

For best results, use this method.

    print(ctable(tobacco$gender, tobacco$smoker), method = "render")

# 4. Using descr() in R Markdown

`descr()` gives good results with both `style = "rmarkdown"` and html rendering.

## 4.1 Rmarkdown Style for descr()

    descr(tobacco, plain.ascii = FALSE, style = "rmarkdown")

### Descriptive Statistics

Pct.Valid | 97.40 | 97.50 | 96.50 | 100.00

## 4.2 HTML Rendering for descr()

We’ll use `table.classes = "st-small"` to show how it affects the table’s size, compared to the `freq()` table rendered earlier.

We’ll also use `message = FALSE` as chunk option to avoid the message saying that non-numerical variables have been ignored.

    print(descr(tobacco), method = "render", table.classes = "st-small")

# 5. Using dfSummary() in R Markdown

To get optimal results, whichever method you choose, it is always best to omit at least 1, and if possible 2 columns from the output. Also, pick carefully the value of the `graph.magnif` parameter.

## 5.1 Grid Style for dfSummary()

Don’t forget to specify `plain.ascii = FALSE` (or set it as a global option with `st_options(plain.ascii = FALSE)`), or you won’t get good results.

(Note: The following output is an image (screenshot). This is because CRAN doesn’t allow writing in “/tmp” or any directory other than R’s temp directory, which would pose problems in terms of column widths. The introductory vignette explains this issue in more details.)

    dfSummary(tobacco,
              plain.ascii  = FALSE,
              style        = "grid",
              graph.magnif = 0.75,
              varnumbers = FALSE,
              valid.col    = FALSE,
              tmp.img.dir  = "/tmp")

### 4.2 HTML Rendering for dfSummary()

This method works really well, and not having to specify the `tmp.img.dir` parameter is a plus.

    print(dfSummary(tobacco,
                    varnumbers   = FALSE,
                    valid.col    = FALSE,
                    graph.magnif = 0.75),
          method = "render")

## 4.3 Managing Lengthy dfSummary() Outputs in R Markdown Documents

For data frames containing numerous variables, we can use the `max.tbl.height` argument to wrap the results in a scrollable window having the specified height, in pixels.

    print(dfSummary(tobacco,
                    varnumbers   = FALSE,
                    valid.col    = FALSE,
                    graph.magnif = 0.75),
          max.tbl.height = 300,

# 5. Using Other Formatting Packages

As explained in the introductory vignette, `tb()` can be used to convert summarytools objects created with `freq()` and `descr()` to simple tibbles, which packages specialized in table formatting will be able to process. This is particularly helpful with `stby` objects:

    library(kableExtra)
    library(magrittr)
    stby(iris, iris$Species, descr, stats = "fivenum") %>%
      tb() %>%
      kable(format = "html", digits = 2) %>%
      collapse_rows(columns = 1, valign = "top")

Species | variable | min | q1 | med | q3 | max
--- | --- | --- | --- | --- | --- | ---
setosa | Petal.Length | 1.0 | 1.4 | 1.50 | 1.6 | 1.9
Petal.Width | 0.1 | 0.2 | 0.20 | 0.3 | 0.6
Sepal.Length | 4.3 | 4.8 | 5.00 | 5.2 | 5.8
Sepal.Width | 2.3 | 3.2 | 3.40 | 3.7 | 4.4
versicolor | Petal.Length | 3.0 | 4.0 | 4.35 | 4.6 | 5.1
Petal.Width | 1.0 | 1.2 | 1.30 | 1.5 | 1.8
Sepal.Length | 4.9 | 5.6 | 5.90 | 6.3 | 7.0
Sepal.Width | 2.0 | 2.5 | 2.80 | 3.0 | 3.4
virginica | Petal.Length | 4.5 | 5.1 | 5.55 | 5.9 | 6.9
Petal.Width | 1.4 | 1.8 | 2.00 | 2.3 | 2.5
Sepal.Length | 4.9 | 6.2 | 6.50 | 6.9 | 7.9
Sepal.Width | 2.2 | 2.8 | 3.00 | 3.2 | 3.8

Using `tb(order = 3)` flips the order of the grouping variable(s) and the reported variable(s):

    stby(iris, iris$Species, descr, stats = "fivenum") %>%
      tb(order = 3) %>%
      kable(format = "html", digits = 2) %>%
      collapse_rows(columns = 1, valign = "top")

variable | Species | min | q1 | med | q3 | max
--- | --- | --- | --- | --- | --- | ---
Petal.Length | setosa | 1.0 | 1.4 | 1.50 | 1.6 | 1.9
versicolor | 3.0 | 4.0 | 4.35 | 4.6 | 5.1
virginica | 4.5 | 5.1 | 5.55 | 5.9 | 6.9
Petal.Width | setosa | 0.1 | 0.2 | 0.20 | 0.3 | 0.6
versicolor | 1.0 | 1.2 | 1.30 | 1.5 | 1.8
virginica | 1.4 | 1.8 | 2.00 | 2.3 | 2.5
Sepal.Length | setosa | 4.3 | 4.8 | 5.00 | 5.2 | 5.8
versicolor | 4.9 | 5.6 | 5.90 | 6.3 | 7.0
virginica | 4.9 | 6.2 | 6.50 | 6.9 | 7.9
Sepal.Width | setosa | 2.3 | 3.2 | 3.40 | 3.7 | 4.4
versicolor | 2.0 | 2.5 | 2.80 | 3.0 | 3.4
virginica | 2.2 | 2.8 | 3.00 | 3.2 | 3.8

# 6. Including dfSummaries in PDF Documents

Here is a recipe for including fully formatted data frame summaries in pdf documents. There is some work involved, but carefully following the instructions given here should give the expected results.

There are basically two parts to this: first, you must create a preamble tex file. Second, you must indicate in the YAML section of your document where to find this file.

### Included Preamble Tex File

This is the content that needs to be included as preamble. You can either copy this into your own tex file, or use the file that is now included in summarytools (as of version 1.0), following the instructions provided below.

    \usepackage{graphicx}
    \usepackage[export]{adjustbox}
    \usepackage{letltxmacro}
    \LetLtxMacro{\OldIncludegraphics}{\includegraphics}
    \renewcommand{\includegraphics}[2][]{\raisebox{0.5\height}%
      {\OldIncludegraphics[valign=t,#1]{#2}}}

If you choose to create a tex file from the above content, the name of the file is arbitrary – you can use whatever name you want. Its location is also up to you. I suggest you put it in the same location as your Rmd file.

Along with the `graph.magnif` parameter for `dfSummary()`, you might need to adjust the `0.5` value used as `raisebox` parameter in the preamble.

### The YAML Section

Your document should start with a YAML header like this one:

    ---
    title: "My PDF With Data Frame Summaries"
    output:
      pdf_document:
        latex_engine: xelatex
        includes:
          in_header:
          - !expr system.file("includes/fig-valign.tex", package = "summarytools")
    ---

If you need to customize the content of the preamble, then your header will look something like this (assuming it is in the same directory as your Rmd document):

    ---
    title: "My PDF With Data Frame Summaries"
    output:
      pdf_document:
        latex_engine: xelatex
        includes:
          in_header: fig-valign-modified.tex
    ---

| The xelatex engine option is not mandatory, but there are several advantages to it. I use it systematically and recommend you do the same.

### R Code

Here is an example setup chunk:

    ```{r, message=FALSE}
    library(summarytools)
    st_options(
      plain.ascii = FALSE,
      style = "rmarkdown",
      dfSummary.style = "grid",
      dfSummary.valid.col = FALSE,
      dfSummary.graph.magnif = .52,
      subtitle.emphasis = FALSE,
      tmp.img.dir = "/tmp"
    )
    ```

And here is a chunk actually creating the summary:

    ```{r, results='asis', message=FALSE}
    define_keywords(title.dfSummary = "Data Frame Summary in PDF Format")
    dfSummary(tobacco)
    ```

### Remarks

Since we redefined the \(\LaTeX\) command `includegraphics`, all images included using `[](some-image.png)` will be impacted. In some cases, this could pose a problem. Eventually, we hope to find a more robust solution, without such side-effects. (If you are well versed in \(\LaTeX\) and think you can solve this problem, please get in touch.)

# 7. This Vignette’s Setup

This vignette uses theme `rmarkdown::html_vignette`. Its YAML section looks like this:

    ---
    title: "Summarytools in R Markdown Documents"
    author: "Dominic Comtois"
    date: "2026-01-27"
    output:
      html_document:
        fig_caption: false
        toc: true
        toc_depth: 1
        css: assets/vignette.css
    vignette: >
      %\VignetteIndexEntry{Summarytools in R Markdown Documents}
      %\VignetteEngine{knitr::rmarkdown}
      %\VignetteEncoding{UTF-8}
      %\VignetteDepends{magrittr}
      %\VignetteDepends{kableExtra}
    ---

The vignette.css file is copied from the installed rmarkdown package’s ‘templates/html_vignette/resources’ directory.

### Global Options

The following global options for knitr and summarytools have been set. Other options might also be useful to optimize content, but this is a good place to start from.

    ```{r setup, include=FALSE}
    library(knitr)
    opts_chunk$set(comment=NA,
                   prompt=FALSE,
                   cache=FALSE,
                   echo=TRUE,
                   results='asis')

    st_options(bootstrap.css     = FALSE,       # Already part of the theme
               plain.ascii       = FALSE,       # Essential setting for Rmd
               style             = "rmarkdown", # Essential setting for Rmd
               dfSummary.silent  = TRUE,        # Hides redundant messages
               footnote          = NA,          # Keeping the results minimal
               subtitle.emphasis = FALSE)       # For the vignette theme,
                                                # this gives better results.
                                                # For other themes, using
                                                # TRUE might be preferable.
    ```

Finally, summarytools CSS has been included in the following manner, before the setup chunck:

    ```{r, echo=FALSE, results='asis'}
    summarytools::st_css(main = TRUE, global = TRUE)
    ```

# 8. Final Notes

This is by no way a definitive guide; depending on the themes you use, you could find that other settings yield better results. If you are looking to create a Word or a PDF document, you might want to try different combinations of options. If you find problems with the recommended settings or if you find better combinations, you are welcome to open an issue on GitHub to suggest modifications or make a pull request with your own improvements to this vignette.
