Exception handling in R [closed]

by

Basically you want to use the tryCatch() function. Look at help(“tryCatch”) for more details.

Here’s a trivial example (keep in mind that you can do whatever you want with an error):

vari <- 1
tryCatch(print("passes"), error = function(e) print(vari), finally=print("finished")) 
tryCatch(stop("fails"), error = function(e) print(vari), finally=print("finished"))
