by_cases: Map cell contents to properties using 'case_when'

In huxtable: Easily Create and Style Tables for LaTeX, HTML and Other Formats

Map cell contents to properties using case_when

Description

This function uses dplyr::case_when() to set cell properties.

Usage

by_cases(..., ignore_na = TRUE)

Arguments

...	A list of two-sided formulas interpreted by case_when.
ignore_na	If TRUE, NA values in the result will be left unchanged from their previous values. Otherwise, NA normally resets to the default.

Details

Within the formulas, the variable . will refer to the content of ht[rows, cols], after conversion to a vector.

case_when returns NA when no formula LHS is matched. To avoid this, set a default in the last formula: TRUE ~ default.

case_when can't deal with brdr() objects, so you cannot use these in by_cases().

Value

A function for use in ⁠map_***⁠ functions.

map_background_color(ht, by_cases(
        . == "a" ~ "red",
        . %in% letters ~ "green",
        . < 0.5 ~ "pink"
      ))
