[R] Prevent saving the workspace while running a script in batch mode

[Jim_S]

Dear R-user,

I'm running a certain R script in DOS batch mode. Is there a way to prevent
R from saving the workspace once this script is finished? I'm asking this
because the resulting .RData file has the size of >70MB. I don't need this
file since my script already writes the required output and this makes the
whole process very slow (>15 minutes each time)


FYI, my script:

setwd("M:/Program Files/Soskat/Models")
library(randomForest)
CT <- read.table("CRD.txt",header=TRUE,sep="\t")
memory.limit(1000)
filename <-
paste("CR",read.table("DTE.txt",header=FALSE,sep="\t"),".Rdata",sep="")
load(filename)
write.table(predict(model, newdata = CT, type = "response"),file="CRP.txt")


and my batch line:

e:\progra~1\R\bin\R CMD BATCH m:\progra~1\soskat\models\CR.r

Thanks in advance,

Jim
