## Arguments

formula a one-sided formula with the "condition" or "column" variable on the right-hand side. A data.frame (or tibble). If this data includes columns called "blocks", "clusters", and/or "weights", the "estimatr" package will consider them when calculating the difference in means. If there is a weights column, the reported mean and standard errors will also be weighted. filename or object type (character string) Supported filename extensions: .html, .tex, .md, .txt, .png, .jpg. Supported object types: "default", "html", "markdown", "latex", "latex_tabular", "data.frame", "modelsummary_list", "gt", "kableExtra", "huxtable", "flextable", "jupyter". Warning: Users should not supply a file name to the output argument if they intend to customize the table with external packages. See the 'Details' section. LaTeX compilation requires the booktabs and siunitx packages, but siunitx can be disabled or replaced with global options. See the 'Details' section. The default output formats and table-making packages can be modified with global options. See the 'Details' section. determines how to format numeric values integer: the number of digits to keep after the period format(round(x, fmt), nsmall=fmt) character: passed to the sprintf function (e.g., '%.3f' keeps 3 digits with trailing zero). See ?sprintf function: returns a formatted character string. Note on LaTeX formatting: To ensure proper typography, all numeric entries are enclosed in the \num{} command from the siunitx LaTeX package by default. This behavior can be altered with global options. See the 'Details' section. string list or vector of notes to append to the bottom of the table. A string with a number of characters equal to the number of columns in the table (e.g., align = "lcc"). Valid characters: l, c, r, S. "l": left-aligned column "c": centered column "r": right-aligned column "d": dot-aligned column. Only supported for LaTeX/PDF tables produced by kableExtra. These commands must appear in the LaTeX preamble (they are added automatically when compiling Rmarkdown documents to PDF): \usepackage{booktabs} \usepackage{siunitx} \newcolumntype{d}{S[input-symbols = ()]} a data.frame (or tibble) with the same number of rows as your main table. a data.frame (or tibble) with the same number of columns as your main table. By default, rows are appended to the bottom of the table. You can define a "position" attribute of integers to set the row positions. See Examples section below. TRUE calculates a difference in means with uncertainty estimates. This option is only available if the estimatr package is installed. If data includes columns named "blocks", "clusters", or "weights", this information will be taken into account automatically by estimatr::difference_in_means. string: "std.error" or "p.value" boolean TRUE escapes or substitutes LaTeX/HTML characters which could prevent the file from compiling/displaying. This setting does not affect captions or notes. all other arguments are passed through to the extractor and table-making functions. This allows users to pass arguments directly to modelsummary in order to affect the behavior of other functions behind the scenes. Examples include: broom::tidy(exponentiate=TRUE) to exponentiate logistic regression. Please see the modelsummary vignette on the package website for important technical notes on this topic. performance::model_performance(metrics="RMSE") to select goodness-of-fit statistics to extract using the performance package (must have set options(modelsummary_get="easystats") first).

## Global Options

The behavior of modelsummary can be affected by setting global options:

• modelsummary_factory_default

• modelsummary_factory_latex

• modelsummary_factory_html

• modelsummary_factory_png

• modelsummary_get

• modelsummary_format_numeric_latex

• modelsummary_format_numeric_html

### Table-making packages

modelsummary supports 4 table-making packages: kableExtra, gt, flextable, and huxtable. Some of these packages have overlapping functionalities. For example, 3 of those packages can export to LaTeX. To change the default backend used for a specific file format, you can use the options function:

options(modelsummary_factory_html = 'kableExtra') options(modelsummary_factory_latex = 'gt') options(modelsummary_factory_word = 'huxtable') options(modelsummary_factory_png = 'gt')

### Model extraction functions

modelsummary can use two sets of packages to extract information from statistical models: broom and the easystats family (performance and parameters). By default, it uses broom first and easystats as a fallback if broom fails. You can change the order of priorities or include goodness-of-fit extracted by both packages by setting:

options(modelsummary_get = "broom") options(modelsummary_get = "easystats") options(modelsummary_get = "all")

### Formatting numeric entries

By default, LaTeX tables enclose all numeric entries in the \num{} command from the siunitx package. To prevent this behavior, or to enclose numbers in dollar signs (for LaTeX math mode), users can call:

options(modelsummary_format_numeric_latex = "plain") options(modelsummary_format_numeric_latex = "mathmode")

A similar option can be used to display numerical entries using MathJax in HTML tables:

options(modelsummary_format_numeric_html = "mathjax")

## Examples

if (FALSE) {
datasummary_balance(~am, mtcars)
}
