R-3.4.1 Running the train function from the latest version of the caret package on CRAN fails with this message: unable to find variable "optimismBoot" The purported workaround is to use devtools::install_github('topepo/caret/pkg/caret') to get the development version. However, that evidently has the same problem with southern hemisphere timezones that install.packages() does -- via download.packages(). i.e. it hangs. The workaround with that one is to use method "internal". What is the equivalent for install_github()?
