arguments in R CMD BATCH mode from Shell

Question

I want to call a R script from a Shell script with R CMD BATCH --no-save --no-restore . How I can transfer a parameter (for example $1 ) from the Shell script into the R script?

Answer 1

As I wrote elsewhere, the BATCH command acts a bit weird sometimes, so I just use the --file command directly:

R --slave --vanilla --file=myScript.R --args foo=2 bar=3 "s=string with spaces" > output.txt

...and then in myScript.R I use args <- commandArgs(TRUE) to get the extra arguments foo etc...
