Comment(by kcrisman):
Okay, the problem is that instead of handling errors, we are ignoring
them:
{{{
# don't abort on errors, just raise them!
# necessary for non-interactive execution
self.eval('options(error = expression(NULL))')
}}}
But see
[http://stat.ethz.ch/R-manual/R-patched/library/base/html/stop.html here]
- it turns out that this is R's way of just totally ignoring them, not
just 'raising' them. This should be fixed.
