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 might be invalid NaN values. I
checked the script output to see if this change was implemented and it was,
but I get the same error.
Any suggestions what to try next?
