Configuration

Variable	Required	Secret	Description
DESIGNR_RSCRIPT	—	—	Optional override for the Rscript binary path. Defaults to whatever 'Rscript' resolves to on the system PATH. Set this if R isn't on PATH or you need a specific R version.
DESIGNR_LAUNCHER	—	—	Optional override for the R launcher path (the inst/launcher.R that sources the R sources and dispatches the JSON). Defaults to the bundled launcher. Set this only if you need to use a non-bundled R source tree.
