Remove Trailing and Leading Characters From Character Strings

Similarly to the function trim from the gdata package, this function can be used to remove trailing and leading spaces from character strings. However, in contrast to trim, any character can be removed by crop.

Usage

crop(x, char = " ")

Arguments

x: character string
char: character to be removed from beginning and end of x

crop(str, "op")
#> [1] " 12  kk " " j    q " "110"
