Dear James,

now the package COPA works well, if the data don't have missing values. Is
that right?
My original data have missing values, so I run pamr.knnimpute to impute
missing expression values. Do you think this is a good procedure? Otherwise
do you have any suggestion?

Best regards
Francesca Guana
