CA
If by CA you mean Correspondence Analysis then see the Environmetrics Task View which list several potential options with an ecological bent: http://cran.r-project.org/web/views/Environmetrics.html You might also consider the Multivariate Task View for a wider selection: http://cran.r-project.org/web/views/Multivariate.html I'm biased but the vegan package would be a good place to start...
