Construct Path to File
Construct the path to a file from components in a platform-independent way.
file.path(..., fsep = .Platform$file.sep)
- character vectors.
- the path separator to use.
The implementation is designed to be fast (faster than
paste) as this function is used extensively in R itself.
It can also be used for environment paths such as PATH and
fsep = .Platform$path.sep.
Trailing path separators are invalid for Windows file paths apart from
/ and d:/ (although some functions/utilities do accept
them), so as from R 3.1.0 a trailing
A character vector of the arguments concatenated term-by-term and
separated by fsep if all arguments have positive length;
otherwise, an empty character vector (unlike paste).
The components are by default separated by
\) on Windows.
