[R] Error: C stack usage is too close to the limit when using list.files()

[Jonathan Greenberg]

Ben:

I'd like to avoid using that (previous version of my code solved it in
that way) -- I would like cross-platform compatibility and I am pretty
sure, along with Windows, vanilla Macs don't come with "find" either
unless XCode has been installed.

Is the list.files() code itself recursive when using recursive=TRUE
(so it has one recursion per bottom-folder)?

--j

P.S. I recognized that in my initial post I indicated using "dir" as
the parameter -- it should have been "path" (the error occurred
through the correct usage of list.files(path="/",...)   That'll teach
me not to copy/paste from my code...
