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.
