If files are numbered, their numbers may not comply with alphabetical order, i.e. "file2.ext" comes after "file10.ext" in alphabetical order. This function renames the files in the specified directory such that they comply with alphabetical order, so here "file2.ext" would be renamed to "file02.ext".
nice_file_nums(dir = ".", pattern = NA)Path (relative or absolute) to the directory in which to do the renaming (default is current working directory).
A regular expression. If specified, files to be renamed are restricted to ones matching this pattern (in their name).
A logical vector with a TRUE for each successful rename
(should be all TRUEs) and a FALSE otherwise.
It works on file names with more than one number in them e.g.
"file01part3.ext" (a file with 2 numbers). All the file names that it works
on must have the same number of numbers, and the non-number bits must be the
same. One can limit the renaming to files matching a certain pattern. This
function wraps nice_nums(), which does the string operations, but
not the renaming. To see examples of how this function works, see the
examples in that function's documentation.
