by_function: Map cell contents to cell properties using a function or scale

Description

This creates a simple wrapper around a function for use in map_xxx. Useful functions include scales and palettes from the scales package.

Usage

by_function(inner_fn, ignore_na = TRUE)

Arguments

inner_fn

A one-argument function which maps cell values to property values.

ignore_na

If TRUE, NA values in the result will be left unchanged. Otherwise, NA normally resets to the default.

Value

A function for use in map_*** functions.

Details

The argument of inner_fn will be as.matrix(ht[row, col]). Be aware how matrix conversion affects the mode of cell data.
