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.
