[R] error-handling question

[ximing wu]

hi,
I have a question about error-handling.  Say I want to do a simulation 100 
times, each experiment involves inverting a matrix. Occasionally the matrix 
is close to singularity,  R gives an error message and the program stops 
right there. Is there any way I can prevent the error message, assign 
something (say a NULL) to the outcome, and move on?

thanks a lot.
