## When running R CMD check on HPC environment with a job scheduler,
## the batchtools registry files must be written to a location on the
## file system that is accessible from all compute nodes. This is
## typically not the case with the default tempdir()/TMPDIR, which
## often is local and unique to each machine
tmpdir <- tempfile(pattern = "R_CMD_check_",

sQuote(tmpdir))
}
}
## Force the .future/ folders to be in this folder
Sys.setenv("R_FUTURE_CACHE_PATH" = file.path(tmpdir, ".future"))
## Make batchtools_<hpc> backends use this as their working directory
