iterating over files in a directory with R

Hello, 

I'm an R newbie and was wondering whether there are R commands for iterating over files in a directory.  Basically what I want to do is to iterate over many files and apply some R functions to each file seperately.  

The apply() and related functions do iteration over various things,
and list.files() and choose.files() select files (the latter
interactively on Windows).

So something like this might do what you want:

 lapply(list.files(), function(x) paste('filename is ',x))
