trim_anything: Trim something other than whitespace
Description
The stringi and stringr packages let you trim whitespace, but
what if you want to trim something else from either (or both) side(s) of a
string? This function lets you select which pattern to trim and from which
side(s).
Usage
trim_anything(string, pattern, side = "both")
Arguments
string
A string.
pattern
A string. The pattern to be trimmed (not interpreted as
regular expression). So to trim a period, use char = "." and not
char = "\\.").
side
Which side do you want to trim from? "both" is the
default, but you can also have just either "left" or "right"
(or optionally the shortened "b", "l" and "r").
