[R] More info on cor()

[Malerba Giovanni]

Dear all,
is there a way to know how many pairs are computed when R performs a
correlation (i.e. cor(x,use="complete.obs"))? (some indivual has no
available information for some variable).
I would like to estimate the  significance of the correlation between 2
variables (hypothesis r=0) and to do this I need to know the sample size.
Thank you.
Giovanni Malerba
