Warning messages: closing unused connections

[irenetorrubia]

It's me again. The code did run*, but returned the following warning:

There were 12 warnings (use warnings() to see them)

warnings() Warning messages: 1: closing unused connection 14 (<-PC:11588) 2: closing unused connection 13 (<-PC:11588) 3: closing unused connection 12 (<-PC:11588) 4: closing unused connection 11 (<-PC:11588) 5: closing unused connection 10 (<-PC:11588) 6: closing unused connection 9 (<-PC:11588) 7: closing unused connection 8 (<-PC:11588) 8: closing unused connection 7 (<-PC:11588) 9: closing unused connection 6 (<-PC:11588) 10: closing unused connection 5 (<-PC:11588) 11: closing unused connection 4 (<-PC:11588) 12: closing unused connection 3 (<-PC:11588) There were 12 warnings (use warnings() to see them)

I assume PC:11588 is my computer. I tried to give a quick look to the code to see if there was a syntax element that could lead to this error, but maybe it is called from another function.

Best,

Irene.

This seems to be tied to the parallel processing. Did you get the correct output? In that case I think it's safe to ignore the warnings. Thanks for reporting and keep 'em coming!

@rdotsch Correct. I think we would want to hide these messages so as not to confuse users, but it's a low priority issue.

[irenetorrubia]

@rdotsch my apologies, I missed the message. It did yield the correct output.

[rdotsch]

These messages only occur if in an earlier run during the same session R was interrupted before it could terminate the parallel processes (which then keep on running). We should catch these kinds of interruptions and kill the parallel processes.
