You can use system() or shell(), which adds "cmd.exe /c " to the front of
your command
so you can use DOS syntax.  Remember to add double quotes when file names
spaces in them.  E.g., I can call an old version of R with the following
and later read its
text output into my current session.

> infile <- tempfile()
> cat("getRversion()\n", file=infile)
> outfile <- tempfile()
> shell(paste("\"C:\\Program Files\\R\\R-2.15.1\\bin\\R\" --quiet --vanilla
<", infile, ">", outfile))
> readLines(outfile)
[1] "> getRversion()" "[1] '2.15.1'"    "> "
