prefix_replace function

prefix_replace

Replace series of characters (usually variable names) at the beginning of a character vector.

prefix_replace(var_names, prefixes, replacements, toTitle = TRUE, ...)

Arguments

• var_names: A character vector, usually variable names
• prefixes: A character vector, usually variable prefixes
• replacements: A character vector of replacements for the prefixes, in the same order as them.
• toTitle: Convert results to Title Case? Defaults to TRUE.
• ...: Other arguments to gsub

Returns

A character vector with prefixes terms in var_names replaced with the content of the replacement terms.

Details

Takes a character vector (usually vector of variable names from a summarized or tidied model object), along with a vector of character terms (usually the prefix of a dummy or categorical variable added by R when creating model terms) and strips the latter away from the former. Useful for quickly cleaning variable names for a plot.

Examples

prefix_replace(iris$Species, c("set", "ver", "vir"), c("sat",
    "ber", "bar"))
