I used linear discriminant analysis (lda) to classify and to 
cross-validate samples of two plant species based on morphometric data 
and to identify the variables that best discriminate between the two 
Because some of the variables are not, and can not be transformed to be, 
normally distributed, I would like to use a non-parametric method.

Are there any R packages that provide methods for non-parametric 
discriminant analysis? Would randomForest 
(http://cran.r-project.org/web/packages/randomForest) be appropriate and 

Thanks for help and best regards
