Rename data frame columns using an alias mapping

Renames the columns of `df` by applying [replace_name()] for each `old`/`new` pair, where each `old` entry may be a `";;"`-delimited set of aliases mapping to a single `new` name.

Usage

rename_all(df, old, new)

Arguments

df

A data frame whose columns should be renamed.

old

A character vector of aliases (each element optionally `";;"`-delimited) identifying columns to rename.

new

A character vector of replacement names, parallel to `old`.

Value

The data frame with renamed columns.
