See the example below (under Ubuntu): $ Rscript -e '1' -e '2' [1] 1 [1] 2 $ Rscript -e '1' -e '' -e '2' ERROR: option '-e' requires an argument $ uname -a Linux xie 3.5.0-25-generic #39-Ubuntu SMP Mon Feb 25 18:26:58 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
Similar problem under Windows: Rscript -e "1" -e "" -e "2" [1] 1 Error: object 'e' not found Execution halted I can certainly save the code in a script and run Rscript foo.R, but I'm curious why Rscript stops when the -e argument is an empty string.
