Thank you so much for the help. apply does work for the first situation.
For the second situation, I'm currently using:

I'm having what looks like a quantization problem with cor on R 2.7.0.
I get warnings from cor.test because r < -1. R session output is at
the bottom. A simple fix would be to add the appropriate checks to
the end of the internal cor code.
