Hello LIST,
In using Rulefit I;ve bee nabel to fit a model using rulefit without
incident. However, when trying to use intnull and interact things go
astray.
> rf=rulefit(x,"N", cat.vars="H",
> not.used=c("G","T"),huber=0.9,path.speed=1);

RuleFit model 2/26/2008 2:17p
ave(abs(error)) terms path steps
84.16 110 8301
> null.mod <- intnull()
[snip building trees and fitting rules]

> int = interact(c("A", "M", "H", "P"), null.mod)
Error in interact(c("A", "M", "H", "P"), null.mod) :
input null.mods inconsistent with RuleFit home directory model.
Something is amiss with the directory but it looks fine (the files from rf
are present and where they should be based on the installation notes) and I
can not figure out what the missing piece here is. Any insight appreciated.
Thanks,
Christopher
