R help - Jul 2001 - More info on cor()

I can't answer the question about knowing how many pairs there
are from "cor", but the way to assess the significance is with
cor.test().  That does tell you.

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
