Summary
PMML is not supported. Here is a workaround.
RevoScaleR's rxDTree objects can be coerced to rpart objects. (Note that rpart is a recommended package that you may need to load.)
library(rpart)
method <- "class"
form <- Kyphosis ~ Number + Start
parms <- list(prior = c(0.8, 0.2), loss = c(0, 2, 3, 0),
split = "gini")
control <- rpart.control(minsplit = 5, minbucket = 2, cp = 0.01,
maxdepth = 10, maxcompete = 4, maxsurrogate = 5, 20 usesurrogate = 2, surrogatestyle = 0, xval = 0)
cost <- 1 + seq(length(attr(terms(form), "term.labels")))
rxDTreeObj <- rxDTree(formula = Kyphosis ~ Number + Start,
data = kyphosis, method = method, parms = parms,
control = control, cost = cost)
pmml(as.rpart(rxDTreeObj))
