[R] parsing dir output for file sizes

I've got an R wrapper around an old DOS program. In the R program I need to
test whether the DOS program failed to produce certain output. This is
indicated by certain text files created by the DOS program being empty.
I can use system(command, intern=TRUE) to get the output of a DOS dir for a
test file, but I'm having trouble parsing this to get the file size.
Is there an R function to find the first occurrence of a character in a
character string (seems there must be, but I'm at a loss to find it)? Or
can anyone suggest a better approach?
