Hi, What is the best general strategy to prevent returned errors from interrupting whatever it is I am running? Only by using options()? This is a problem for me in 2 particular cases: (i) An error breaking my loops. (ii) I would like to run some regressions where it automatically will try a specified number of increasingly robust options until the regression doesn’t fail. Using try(), especially for the second case, seems a bit clunky for my needs. As I’ve never really automated the handling of my errors I was wondering if there is perhaps a bit of simple wisdom or pointers in the right direction on the matter.
