Xgboost 这个包直接用 R CRAN 的镜像就可以，不需要用'dmlc.ml'的。其中选择国内的镜像(mirrors.tuna.tsinghua.edu.cn)下载快一些，其中清华的比中科大、同济的都要稳定。

> install.packages("xgboost")
试开URL’https://mirrors.tuna.tsinghua.edu.cn/CRAN/bin/windows/contrib/3.6/xgboost_0.90.0.2.zip'
Content type 'application/zip' length 2333360 bytes (2.2 MB)

package ‘xgboost’ successfully unpacked and MD5 sums checked

The downloaded binary packages are in
    C:\Users\lijiaxiang\AppData\Local\Temp\RtmpsPAbwg\downloaded_packages

镜像的设置方法，打开RStudio，点击 Tools，Global Options，Packages，

如果还不行的话，下次跑这行命令sessionInfo()，把输出都复制上来我看下。
