I want to create a visual display such that instead of #s for the p- values,
I have a circle sized to represent the size of the p-value.

Wouldn't that convey exactly the wrong information? Unless that is p- value has some sort of non-statistical meaning?

symbolys() is what I've found to do this, but it isn't clear to me how to
format the input for the function.

Any suggestions? or help? Even a link if someone else has asked the question
and it's been answered would be helpful.
