[R] question on suppressing error messages with Rmath library

[Ranjan Maitra]

Thanks, Jim and Ronggui! This would work, of course!

But I apologize for not being clear in the first post. I am calling Rmath from a C program. I could not figure out how to set this without going back and recompiling: the message in in pnt.c and pulls it from the header file nmath.h.

Thanks,
Ranjan

However, to have this happen a huge number of times, when the optimizer is churning through the dataset is bothersome, but more importantly, a bottleneck in terms of speed. Is it possible to switch this off? Is there an setting somewhere that I am missing?
