[R] How to personalize the rpart function: t.default(x)

[Rolf Turner]

t is for transpose; look at ?t, ?t.default,
?t.data.frame

Bottom line:  Somewhere in your code you are trying to transpose
something that is not a matrix.  (Or you are passing to an existing
function an object which that function expects to be a matrix, but
isn't.)
