Manipulate filename extensions
Functions to obtain (file_ext()), remove (sans_ext()), and
change (with_ext()) extensions in filenames.
file_ext(x) sans_ext(x) with_ext(x, ext)
x |
A character of file paths. |
ext |
A vector of new extensions. It must be either of length 1, or the
same length as |
file_ext() is similar to tools::file_ext(), and
sans_ext() is similar to tools::file_path_sans_ext().
The main differences are that they treat tar.(gz|bz2|xz) and
nb.html as extensions (but functions in the tools package
doesn't allow double extensions by default), and allow characters ~
and # to be present at the end of a filename.
A character vector of the same length as x.
