[R] How to catch errors regarding the hessian in 'optim'

I am weighing in even though I know nothing.

in tryCatch define an error handler

error = function(e){

    text <- print(e)        # surely there must be better ways
    
    # parse text for substring 'optim' or more strongly characteristic substrings 
    # you have already seen to emerge from optim
    # do what you have to do if such is detected
}


Sorry if this answer seems trivial.
