Automatically Delete Files/Folders in R

Is there any way to automatically delete all files or folders with few R command lines?
I am aware of the

unlink()
or
file.remove()
functions, but for those you need to define a character vector with exactly all the names of the files you want to delete. I am looking more for something that lists all the files or folders within a specific path (e.g. 'C:/Temp') and then delete all files with a certain name (regardless of its extension).

Any help is very much appreciated!

Answer

Maybe you're just looking for a combination of file.remove and list.files? Maybe seomthing like:

do.call(file.remove,list(list.files("C:/Temp", full.names=TRUE)))

And I guess you can filter the list of files down to those whose names match a certain pattern using grep or grepl, no?
