Hello,
Works with me, but I'm using R v 3.3.0. Note that your version of R is
over 1 year old, try updating it.
install.packages("caret")
install.packages("e1071")
library(caret)
library(e1071)
set.seed(100)
tr.control <- trainControl(method="cv", number=10)
class(tr.control)
[1] "list"
Hope this helps,
Rui Barradas
