Thanks Dirk!  However, I'm trying to pass several numbers as a single
argument, which should be turned into a numeric vector, and doing
as.numeric() fails:

$ r littler_ex.R 14 '3, 2'
[1] NA

,-----[ cat ~/scripts/R/littler_ex.R ]
| ff <- as.numeric(argv[1])
| ss <- as.numeric(argv[2])
| print(ff * ss)
`-----

I know I could simply pass each number as a separate arg, but I already
have 6 args to handle.  I didn't find an example for this situation in the
examples.  Thanks.
