This function uses dplyr::case_when() to set cell properties.
by_cases(..., ignore_na = TRUE)A list of two-sided formulas interpreted by case_when.
If TRUE, NA values in the result will be left unchanged
from their previous values. Otherwise, NA
normally resets to the default.
A function for use in map_*** functions.
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().
Other mapping functions:
by_colorspace(),
by_function(),
by_quantiles(),
by_ranges(),
by_regex(),
by_rows(),
by_values()
