That's the only way. The `working directory' is the directory from which
you launch an application (although you can fix that by a shortcut). R
looks in the working directory for several things, e.g. a .Rprofile file,
before it ever runs any R code like setwd. If that is not a problem you
can use something like (from a decent shell)
(echo "setwd(somewhere"); cat test.r) | Rterm.exe --args "Arg1"
to make the first R code run change directories. Or you can have at the
top of test.r
setwd(Sys.getenv("WD"))
and use
Rterm.exe WD="c:/data" < test.r --args "Arg1" "Arg2"
