fmt_missing: Format missing values

In gt: Easily Create Presentation-Ready Display Tables

Description

Wherever there is missing data (i.e., NA values) a customizable mark may present better than the standard NA text that would otherwise appear. The fmt_missing() function allows for this replacement through its missing_text argument (where an em dash serves as the default).

Usage

fmt_missing(data, columns, rows = everything(), missing_text = "---")

Arguments

data	A table object that is created using the gt() function.
columns	The columns to format. Can either be a series of column names provided in c(), a vector of column indices, or a helper function focused on selections. The select helper functions are: starts_with(), ends_with(), contains(), matches(), one_of(), num_range(), and everything().
rows	Optional rows to format. Providing either everything() (the default) or TRUE results in all rows in columns being formatted. Can either be a vector of row captions provided in c(), a vector of row indices, or a helper function focused on selections. The select helper functions are: starts_with(), ends_with(), contains(), matches(), one_of(), num_range(), and everything(). We can also use expressions to filter down to the rows we need (e.g., [colname_1] > 100 & [colname_2] < 50).
missing_text	The text to be used in place of NA values in the rendered table.

Details

Targeting of values is done through columns and additionally by rows (if nothing is provided for rows then entire columns are selected). Conditional formatting is possible by providing a conditional expression to the rows argument. See the Arguments section for more information on this.

Value

An object of class gt_tbl.

  fmt_missing(
    columns = 1:2,
