Correlation matrix one side with significance

Hi there!

In my case, 

cor(d[1:20])

makes me a good correlation matrix.

Now I'd like to have it one sided, means only the left bottom side to be
printed (the others are the same) and I'd like to have * where the
p-value is lower than 0.05 and ** lower than 0.01.

How can I do this?

And another thing: Is there a way to output that table as a latex table?

Thanks,
Martin
