Hi,
I have a xxx.R file. In order to run this file, I have
to go to R, and type -- source("xxx.R").
Two questions:
1. How to run file xxx.R under DOS prompt instead of
entering R environment?
2. There are several functions in file xxx.R, how to
pass the arguments
to the function when I try to run this file via
source() function (or under DOS mode)?
Thanks,
Yu-Ling Wu

For example, you might have myfunc <- function(x) { print(x) } in xxx.R. If you want to call myfunc(34), then first source the file, then execute myfunc(34). If doing it in batch mode, copy the file to a temp file, add the line "myfunc(34)" to the end, and execute the temp file.

There is no version of R that runs under DOS.> 2.
