Like you'd program any exception handling.  A toy example to get you 
started might look like this:

(somewhere inside your script file)
...
results <- vector(length=200,mode="numeric") #or whatever you use
set.seed(123)
...
errors <- list()

for(ii in 1:200) {
   foo <- try(some.simulation.thingy(your.params))
   if(inherits(foo,"try-error")) { #something bombed
     results[ii] <- NA
     errors[[as.character(ii)]] <- foo
   } else { #it worked
     results[ii] <- foo
   }
}
...
save(results,errors,file="results+errors.RData")
...
The end.

Play with that, and see if you get some useful ideas.

Cheers
