Skipping error in for-loop

Question

I am doing a for loop for generating 180 graphs for my 6000 X 180 matrix (1 graph per column), some of the data don\'t fit my criteria and i get the error:

Answer 1

Here's a simple way

for (i in 1:10) {

  skip_to_next <- FALSE

  # Note that print(b) fails since b doesn't exist

  tryCatch(print(b), error = function(e) { skip_to_next <<- TRUE})

  if(skip_to_next) { next }     
}

Note that the loop completes all 10 iterations, despite errors. You can obviously replace print(b) with any code you want. You can also wrap many lines of code in { and } if you have more than one line of code inside the tryCatch
