RE: [R] Rcmd BATCH command line arguments

Okay, thanks. But it seems inconsistent that Rterm and Rgui support setting environment variables this way while Rcmd does not. Also, I don't think the rw-FAQ is all that helpful on this issue. It says: Environment variables can be set in R in three different ways. 1. On the command line as
