Translate column names of a data.frame or lazy tibble using a dictionary

This function allows renaming column names in an input object (a data.frame or tbl_lazy) by translating them with a user-supplied dictionary. Users can choose to translate column names from "old" to "new" or vice versa.

Usage

dr_translate(d, dictionary, from = "old", to = "new")

Arguments

d: A data.frame or tbl_lazy object whose column names need to be translated.
dictionary: A data.frame (or tibble) with at least two columns: from and to (default names are "old" and "new"). The from column contains the current column names in d, and the to column contains the new column names to translate to.
from: A string specifying the column name in dictionary to use for current column name matching. Defaults to "old".
to: A string specifying the column name in dictionary with new column names to translate to. Defaults to "new".

Value

An object of the same class as d with column names translated.

Examples

# Example dictionary
dictionary <- data.frame(
    old = c("Ship", "SweepLngt"),
    new = c("Platform", "SweepLength")
)
# Example data
df <- data.frame(Ship = "26D4", SweepLngt = 110)

dr_translate(df, dictionary)
#>   Platform SweepLength
#> 1     26D4         110
