Contructs path to a file from components in platform-independent manner
Usage
fullfile(...)
Arguments
...
character strings representing path components
Value
Returns character vector of arguments concatenated term-by-term and
separated by file separator if all arguments have a positive length;
otherwise, an empty character vector.
Details
Builds a full filename from the directories and filename specified. This
is conceptually equivalent to paste(dir1, dir2, dir3, filename, sep = \link{filesep})
with care taken to handle cases when directories begin or end with a
separator.
