R help - Oct 2008 - Interpretation in cor()

Hello,

I am performing cor() of some of my data. For example, I'll do 3 corr()
(many variables) operations, one for each of the three treatments.

I then do the following:

i <-lower.tri(treatment1.cor)
cor(cbind(one = treatment1.corr[i], two = treatment2.corr[i], three
treatment3.corr[i]))

Does this operation above tell me how correlated each of the three
treatments is? Because this how I am interpreting it.

Thanks,
Michael Just

Please provide a small working example. It is difficult to see what you are
doing from the description below.
