I learned how to use `R CMD BATCH`. It's definitely more painful than `Rscript -e`, but at least the following works: EXEC_DIR='/share/linux86_64/bin' # on foo, at least # EXEC_NAME='Rscript' EXEC_NAME='R' EXEC_PATH="${EXEC_DIR}/${EXEC_NAME}" BATCH_INPUT_PATH="./junk.r" # presumably in home dir BATCH_OUTPUT_PATH="./junk.r.out" # ditto for RSERVER in 'foo' 'bar' 'baz' ; do echo -e "${RSERVER}:" # The following 3 commands attempted to debug a # separate but related problem; about which, see # http://serverfault.com/questions/424027/ssh-foo-command-not-loading-remote-aliases # ssh ${RSERVER} "${EXEC_NAME} --version | head -n 1" # ssh ${RSERVER} "grep -nHe 'bashrc' ~/.bash_profile" # ssh ${RSERVER} "grep -nHe '\W${EXEC_NAME}\W' ~/.bashrc" ssh ${RSERVER} "${EXEC_PATH} --version | head -n 1" ssh ${RSERVER} "echo -e 'as.numeric(suppressWarnings(suppressPackageStartupMessages(require(M3))))\n' > ${BATCH_INPUT_PATH}" ssh ${RSERVER} "rm ${BATCH_OUTPUT_PATH}" ssh ${RSERVER} "ls -al ${BATCH_INPUT_PATH}" ssh ${RSERVER} "cat ${BATCH_INPUT_PATH}" ssh ${RSERVER} "${EXEC_PATH} CMD BATCH --slave --no-timing ${BATCH_INPUT_PATH} ${BATCH_OUTPUT_PATH}" ssh ${RSERVER} "ls -al ${BATCH_OUTPUT_PATH}" ssh ${RSERVER} "head -n 1 ${BATCH_OUTPUT_PATH}" echo # newline done Given the pain, I'd still like to know: > 2 What should my admin have done to install both Rscript and R? > (Alternatively, what should I tell my admin to do in order to make > both Rscript and R available?) > 3 Is there any reason to install R without Rscript?
