I know an answer for Unix that can perhaps you can translate to DOS.
If you pass a file of R statements to 'R' on the command line it will
run them. In Unix, the '|' (pipe) symbol sends text to a program as
though it came from a file, thus:
echo "x<-2; 2*x" | R --vanilla --slave
yields
[1] 4
Or you could put "x<-2; 2*x" in a file called test.R and run:
R --vanilla --slave < test.R
I use this to interpret user commands from labsynch wiki pages on the
server ( I learned this from Alfredo Pontillo's R-php). You can run
any R command, including loading other files and libraries. I use it
to pass files and set the working directory.
