strtrim in r

The strtrim function in R is used to trim leading and trailing whitespace from a character string. The function takes three arguments: x which is the character vector to be trimmed, width which is the maximum width of the output, and side which specifies whether to trim from the left, right, or both sides of the string. If width is not specified, the default is to remove leading and trailing whitespace. If side is not specified, the default is to trim from both sides. The function returns a character vector of the same length as x, with leading and trailing whitespace removed according to the specified width and side parameters.
