Witryna297 2 3 8 You probably have factors. Use sapply (species, class), not mode, since mode will still give numeric for factor s – Ricardo Saporta Mar 14, 2014 at 15:51 Add a comment 1 Answer Sorted by: 14 Instead of using 'mode', you should be testing with 'class'. You probably have a factor column. http://factominer.free.fr/missMDA/PCA.html
