Hi, Thanks so much for the hints, I think I've cracked it! The key is to create a dummy function, "continue_on_error" which gets run instead of "stop" when an error occurs, then reference it with options(error=continue_on_error). Here's an example:
========================== continue_on_error <- function() { print("NOTE: THERE WAS AN ERROR HERE. We are continuing because we have set 'options(error=continue_on_error())'") } testfunc <- function(a,b) { print(a+b) } # This is the key option options(error=continue_on_error) print(1) print(2) # This should work testfunc(a=10, b=10) print(3) # This should produce an error and stop the Rscript run normally testfunc(a=1) print(4) print(5) ========================== Running this via Rscript completes: Rscript continue_on_error.R ================ [1] 1 [1] 2 [1] 20 [1] 3 Error in print(a + b) : argument "b" is missing, with no default Calls: testfunc -> print [1] "NOTE: THERE WAS AN ERROR HERE. We are continuing because we have set 'options(error=continue_on_error())'" [1] 4 [1] 5 ================ If you comment out the options() line you get: Rscript continue_on_error.R ================ [1] 1 [1] 2 [1] 20 [1] 3 Error in print(a + b) : argument "b" is missing, with no default Calls: testfunc -> print Execution halted ================ ...which was what was annoying me before. So, life hack FTW. (Of course, yes, it would be better to write code good n stuff, but for quick and dirty things this is handy.) Cheers!
