[BioC] stam:in.local(.Object, ...):couldn't find function "balanced.folds"

[Saurin D. Jani]

Hi,

I am using package stam. and trying to cross validate various graph shrinkage
candidates. 

 esetSub2Train is my training set. 

> esetSub2Train.cv <-
stam.cv(esetSub2Train,pData(esetSub2Train)[,"scanner2"],chip = "moe430a",root=
"GO:0006954");
registered 0 of 0 visited nodes
registered 20 of 48 visited nodes
Error in .local(.Object, ...) : couldn't find function "balanced.folds"

has anyone encountered this error?

Regards,
Saurin Jani
