There is a bug with this Caret package version and RRegrs. The 'undefined column selected' problem with models using RFE feature selection.

follow these steps and report in order to know if there exist other versions with the bug:

#please check caret version
packageVersion('caret')

#remove this version and the bug
remove.packages(c('caret'))

library(devtools)

#install Caret Package version 6.0.52
install_version(package='caret',version='6.0-52')
