Current R release (3.5.2) and devel return a 0 exit status on error,
while prior versions returned a non-zero exit status. On Linux and
MacOs, the following line returns TRUE for R-3.5.2 and R-devel, and
FALSE for R-3.5.1 and R-3.5.0:
system2("Rscript", c("-e", shQuote("stop('foo')"))) == 0
I didn't find this in the NEWS, so I believe this is a bug.
Best,
Michel
