The dimension 1 explained 43% of the variance. Then, I was wondering
which values I could use like PC1 in PCA. I explored in mjca1 and found
"rowcoord".

Customizing a Plot in Correspondence Analysis
Hello,
Using the Correspondence Analysis package (ca), I wonder if there is a way
to further customize the plot beyond the options given in plot.ca provided
by the mentioned package.
The correspondence analysis I am doing consists of two datasets sharing
only the rows, so the plot draw the total of columns (from both datasets)
in the graph and the rows as expected. However, as in my case the

Scores in Dimensions in Correspondence Analysis
Hi R,
I was experimenting with the CA package for correspondence analysis.
data(author)
ca(author)
plot(ca(author))
How can I get the values used by the plot for the two axis for biplot?
In other words, how will I be able to obtain the scores in the
dimensions (which are obtained by PCA) of the graphs? Thanks.
Thanks and Regards,
Shubha
