[R] running a function repeatedly on error....

[akshay kulkarni]

Dear members,
                          I have a function FUN1 that downloads some data from the internet. It so happens that the function doesn't work the first time, but on the second or third attempt it works. I want to run the function repeatedly for four times if it throws an error:

X <- tryCatch(FUN1, error = function(c) {FUN1})

This runs the function two times. But I want to run the function four times if throws an error, but on the fifth attempt if it throws an error, abort. I know I can include the tryCatch call inside FUN1 and call it, but any short and elegant code to that effect?

Thanking you,
Yours sincerely
AKSHAY M KULKARNI
