遇到很久的一个问题，用devtools::install_github()
安装github上的包总是报错，Installation failed: 调用命令时发生了错误
现在终于解决了,设置options(unzip = 'internal')
如果是链接问题可设置
options(download.file.method = "wget")
or
options(download.file.method = "libcurl")
> devtools::install_github('ramnathv/rCharts')
Downloading GitHub repo ramnathv/rCharts@master
