I was facing this issue and this workaround worked for me. Maybe this should be moved to know issues section.

R package for xgboost
|
|
=====================
|
|
|
|
Installation
|
|
------------
|
|
|
|
For up-to-date version (which is recommended), please install from github. Windows user will need to install [RTools](http://cran.r-project.org/bin/windows/Rtools/) first.
|
|
|
|
```r
|
|
devtools::install_github('dmlc/xgboost',subdir='R-package')
|
|
```
|
|
|
|
Examples
|
|
--------
|
|
|
|
* Please visit [walk through example](demo).
|
|
* See also the [example scripts](../demo/kaggle-higgs) for Kaggle Higgs Challenge, including [speedtest script](../demo/kaggle-higgs/speedtest.R) on this dataset and the one related to [Otto challenge](../demo/kaggle-otto), including a [RMarkdown documentation](../demo/kaggle-otto/understandingXGBoostModel.Rmd).

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) :
|
|
Peer certificate cannot be authenticated with given CA certificates
|
|
```
|
|
To get around this you can build the package locally as mentioned [here](https://github.com/dmlc/xgboost/issues/347) -
|
|
```
|
|
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.
|
|
```
