I am trying to use the plotmo package to generate a partial dependence

rpart predict function does indeed return 204938 results, but plotmo is
supposed to be able to handle NA's in rpart models. What I might do about
this?
It’s because you have NAs in y; plotmo only allows them in x (and then only
with rpart models). The plotmo help page is admittedly not clear on this
and I will update it in due course.
