[R] handling breaks in a for loop

[Ebert,Timothy Aaron]

Is the bug in the data or in the code?
Can you identify the cause? Can you get a subset of the data to find the bug using fewer resources?
If you can identify the root cause, then you can set an error trap.
If the error is a memory problem, they you either need to save, reallocate memory, or get more memory.

Subject: [R] handling breaks in a for loop

[External Email]

dear members,
                         I have a very large for loop (basically a web scraping loop) with 500 iterations(over different stocks). I am concerned about the loop breaking midway.

My question is: is there any method to store the succesful iterations and continue with the iteration (ofcourse, after fixing the bug) where the exception occured? I can insert a save () function in the body of the loop and save the succesful iterations but this would slow down the execution speed. Any other method? I want to avoid trycatch as much as possible because an NA in the place of a succesful iteration would cost me much.

Thanking you,
Yours sincerely,
AKSHAY M KULKARNI
