[R] Using system to run a stand alone program that requires input in Windows

Under Windows I want to run a stand alone program that takes a number
of commands from the user. I've been running the program from the
command line using <

C:\Data\> foo.exe < params.txt

where foo is the program is params.txt is a text file with a few lines
(9) of parameters.

I want to run this from R using system a la:

system("foo.exe", input = "params.txt")

but that doesn't do it. What am I missing?
