David, Thanks for forwarding this to me.
Yonas, Please try updating your ca package to version 0.61 which fixes
this issue. This is not the latest official CRAN version, so get it from
R-forge via
> update.packages("ca", repos = "http://r-forge.r-project.org";)
All the best,
Oleg.

I have used ca() in the past and extracted more than two dimensions from
similar tables.
