An integer will be added as suffix in x if an identical value is in y.
If a value with suffix is already in y, the function will search for the
highest suffix to avoid duplicated values.
Usage
add_suffix(x, y, sep = "_")
Arguments
- x
(character of length 1) The name to be compared.
- y
(character) Existing names, with or without suffixes.
- sep
(character of length 1) Symbol to be placed between the original
name and the suffix.
Value
A character value, either x or x with suffix if already in y.
