R help - Nov 2007 - Canonical Correlation Analysis

Dear Sir/Madam,
                             This is Animesh working on Canonical
Correlation Analysis ( CCA ) and I am using CCA package in R. I have a doubt
and it may be very basic question. Hope someone will  get back to me with
answer. I am trying to follow the documentation of CCA but could not make
out some of the stuffs.

1) I simulated some of the data sets and got the result. I want to ask you
why there are two circles in the plots? and what does it mean? And also how
it decidces the center of the Circle.
2) X and Y axis values in between 1 and -1 . Is it due to max and min values
of correlation .
3) what is the dimensions means in X and Y axis?

It will be very useful if someone help me out with probable solution.

Thanks for your time

Animesh

Animesh,

In order to get useful help, you should post the code you used to simulate your
data, run the CCA, and create the plot, so we can see what you are seeing (as
the posting guide suggests).
