command files

Since I'm a SAS programmer, I'm used to creating command files in an editor for submission later.  Is there a way to do this in R?  I'd need to retain an ouput listing and a log to check for errors.

You probably want R CMD BATCH from a command-line. For example, if myjob.R is:

x=runif(100)
y=runif(100)
m=lm(y~x)
summary(m)

 and I do:

R CMD BATCH myjob.R

from a command prompt then when it finishes I get a file "myjob.Rout"
which is a transcript file just like you'd see if you did things
interactively.

 Normally on a Unix box 'R' will be in your path so you can type it
just like that from a terminal window. From Windows, I'm not so sure,
so you may have to type the full path, like:

C:\Program Files\R-2.8.0\bin\R.exe CMD BATCH myjob.R
