Capturing Rscript errors in an output file

linux r rscript

Unlike the similar command R CMD BATCH which by default produces an output file which contains any error messages which would cause the execution of a script to halt, I have not been able to find a way to do this with Rscript. I have tried using a pipe in my linux shell to achieve this:

RScript --no-save --no-restore --verbose myRfile.R > outputFile.Rout

but this will only pipe over any output that occurred before an error occurs, so the file outputFile.R doesn't contain any error information. Does anyone know how to get the capture any errors that occur in executing an R file using RScript and saving it to a file?

Rscript --no-save --no-restore --verbose myRfile.R > outputFile.Rout 2> errorFile.Rout

To put the output and error in the same file (assuming sh/bash)

Rscript --no-save --no-restore --verbose myRfile.R > outputFile.Rout 2>&1
