    This works for me: 

    R CMD BATCH myscript.R

    As an example, the following should produce a .csv file of a random generated matrix. I have always named this scripts with an “.R” extension, but I’m not sure that that is necessary.

    The script to call (named “testscript.R”) contains the following lines of code:

    set.seed(1)
M<-matrix(runif(20),5,4)
write.csv(M, file="M.csv")

    Then call this script in your console as illustrated above:

    R CMD BATCH testscript.R

    On my machine, this produces the “M.csv” document, which looks like this:

        "","V1","V2","V3","V4"
"1",0.2655086631421,0.898389684967697,0.205974574899301,0.497699242085218

    Also, a “testscript.Rout” file is produced giving the R console output:
