I am not sure what you can gain by looking at more decimal points in  
a correlation, but there are two ways, as far as I can tell:

1) Wrap the command in "print", and use the digits optional argument  
in print. Have a look at ?print for details
2) Change the default more permanently for the session, by something  
like
options(digits=10)
Look at ?options for details

We would need a reproducible example for this, I think.
