```r

drat:::addRepo("dmlc")
install.packages("xgboost", repos="http://dmlc.ml/drat/", type="source")

***Important*** Due to the usage of submodule, `install_github` is no longer support to install the
latest version of R package. 
For up-to-date version, please install from github. Windows user will need to install [RTools](http://cran.r-project.org/bin/windows/Rtools/) first.

```bash

cd xgboost
make Rbuild
