Hello group,
I created an Expression Set as following:
> esetSub
Expression Set (exprSet) with
4986 genes
12 samples
phenoData object with 2 variables and 12 cases
varLabels
cov1: Genotype
cov2: Treatment
> Y<-factor(esetSub$cov1)
> table(Y)
Y
0 1
6 6
Then I want to do rpart:
> X<-t(exprs(esetSub))
> library(rpart)
> df<-data.frame(Y=Y, X=X)
> tr<-rpart(Y ~ ., data=df)
Then I got the following error:
"Error: protect(): stack overflow"
Any suggestion? Thank you!
Xin LIU
