Replacing ids <- rownames(features) with ids <- rownames(predicted) is the only edit I did after the previous try, so this should have solved the error. If I understood correctly na.action = na.exclude can help to work around the NA values without deleting rows but somehow I did not work. The

[GRASS-user] v.class.mlR Error in data.frame : arguments imply differing number of rows

Dear Moritz and other Grass- users and developers, I tried dealing with the error myself by changing predicted <- data.frame(predict(models.cv, features)) into predicted <- data.frame(predict(models.cv, features, na.action = na.exclude)), based on discussions online implying some predictions
