In mbadge/MyUtilsR: Personal Utility Functions for All Of My Machines

Description

Map Names Flexibly in a Data.Frame or Vector A wrapper for 'mapvalues' (which only supports vectors, not data frames), with the same mapping rules. 'from' and 'to' must have equal lengths.

Usage

mapnames(df, from, to)

Arguments

df	: a data frame whose names need changed
from	: a character vector with old col names.
to	: a character vector with new col names.

Value

df : a dataframe with the same values as input, but possibly replaced colnames

Examples

# DF Operand
mapnames(mtcars,
         from = c("cyl", "hp"),
         to   = c("cylinders", "horsepower"))
# Nmd Vector Operand
mapnames(mtcars$cyl %>% set_names(),
         from = c(4, 6),
         to   = c("four", "six"))
