[R] Correlation of coefficients?

[asako Ishii]

Hi R users!

One thing I cannot understand with R is the frequently appearing "
Correlation of coefficients". I do not find a through going explanation
of this concept either on the help pages of R or on the internet. A
Google search has shown many examples of R/S-Plus outputs but no
explanations of meaning.

I am afraid this turns out to be a silly and unworthy question. Would
anyone be kind enough to show relevant literature or a text book to a
layperson studying on his/her own? 

Thanks in advance.
