Hi All,I am writing a function that reads a file in myfile = file('myfile.raw', 'rb') . . . . . close(myfile) No matter what, I get the warning Warning message: closing unused connection 3 (myfile.raw) Since the whole thing is in a function, I'd like to avoid unecessary noise for the user, and I'd like to kill the warning -- without having to mess with global options. Any ideas how?
Make sure the connection (not 'file') is really closed. That message indicates that close(myfile) was never called.
A good way to do this is to use on.exit() in your function.

Hmm, how long have you been asking questions here? Following the posting guide is way overdue. We should not have to guess what error you made in the code you failed to show us.
