Details
The pattern language is based on that of the bash shell. An asterisk matches
zero or more characters, a question mark represents one character, and a collection
of characters within square brackets matches any one of those characters.
Inside of square brackets you may also use x-y to mean any of the characters
between x and y, ordered in the ASCII order.
Value
A character vector containing paths to files that match the patterns in the input paths.
Examples
Sys.glob(file.path(.libPaths(), "[k-m]*", "DESCRIPTION"))
Sys.glob(file.path(R.home(), "*library"), dirmark=TRUE)
