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
On Windows if you grab Rcmd.bat from http://batchfiles.googlecode.com and place it anywhere in your PATH then you can do the above like this: Rcmd BATCH myjob.R without having to set any paths. Rcmd.bat and all other batch files in that collection, are self contained so installation is just a matter of placing whichever you need anywhere on your path. Rcmd.bat finds R by looking into the registry and then runs it.
