things like these  remind me once more  
how very useful it would be to have an option like
	-dont-stop-on-error
for R (batch).

We could have many tests like these in a few  'test' files that would be
run through R...; 
Actually, I'm thinking of auto-generated function calls where most would
give  'Error: ..'  but none should give  segfault...

This could help very much to autodetect problems like these.

- Martin.
