Map cells matching a string or regex to cell properties

Description

by_regex() sets properties on cells which match a regular expression.

Usage

by_regex(..., .grepl_args = list(), ignore_na = TRUE)

Arguments

...	A list of name-value pairs. The names are regular expressions. If there is a single unnamed argument, this is the default value for unmatched cells. More than one unnamed argument is an error.
.grepl_args	A list of arguments to pass to grepl(). Useful options include fixed, perl and ignore.case.
ignore_na	If TRUE, NA values in the result will be left unchanged from their previous values. Otherwise, NA normally resets to the default.
