summary: e.g., how to replace '<query R for package=package_name>' in the following:
for RSERVER in 'foo' 'bar' 'baz' ; do ssh ${RSERVER} '<query R for package=package_name>' done or is there a better way to script checking for an R package? details: For my work I need a few non-standard R packages. I do that work on 2 clusters. One uses environment modules, so any given server on that cluster can provide (via `module add`) pretty much the same resources. The other cluster, on which I must also unfortunately work, has servers managed individually, so I get in the habit of doing, e.g., EXEC_NAME='whatever' for S in 'foo' 'bar' 'baz' ; do ssh ${RSERVER} "${EXEC_NAME} --version" done periodically. I'm wondering, what incantation to utter (bash preferred) via ssh to query a given server's R for a given package?
