When performing a dplyr::left_join(), the suffix argument allows the user
to replace the default .x and .y that are appended to column names shared
between the two data frames. This function allows a user to convert those
suffixes to prefixes.
rename_prefix(df, suffix = c(".x", ".y"), punct = TRUE)A joined data frame.
If there are non-joined duplicate variables in x and y, these suffixes will be added to the output to disambiguate them. Should be a character vector of length 2. Will be converted to prefixes.
logical; Should punctuation at the start of the suffix be
detected and placed at the end of the new prefix? TRUE by default.
A data frame with new column names.
a <- data.frame(x = letters[1:3], y = 1:3)
b <- data.frame(x = letters[1:3], y = 4:6)
df <- dplyr::left_join(a, b, by = "x", suffix = c(".a", ".b"))
rename_prefix(df, suffix = c(".a", ".b"), punct = TRUE)
#> x a.y b.y
#> 1 a 1 4
#> 2 b 2 5
#> 3 c 3 6
