It could be that the operating system is so locked down that the user cannot call external software via system(), which can lead to obscure errors such as:
Error in system(cmd, intern = TRUE, input = input) :
'CreateProcess' failed to run 'some_external_software'
Adding an internal assert_system_is_supported() that checks this, and gives an informative error message when not supported, would be useful. It could, for instance, test that:
out <- system2(file.path(R.home("bin"), "Rscript"), args = "--version", stdout = TRUE)
works. The result could be memoized, so that the test is one done once per R process.
