Notes
If you face an issue installing the package using devtools::install_github, something like this (even after updating libxml and RCurl as lot of forums say) -
devtools::install_github('dmlc/xgboost',subdir='R-package')
Downloading github repo dmlc/xgboost@master
Error in function (type, msg, asError = TRUE) :

To get around this you can build the package locally as mentioned here -
1. Clone the current repository and set your workspace to xgboost/R-package/
2. Run R CMD INSTALL --build . in terminal to get the tarball.
3. Run install.packages('path_to_the_tarball',repo=NULL) in R to install.
