是否有可用于R 3.1.1的rCharts版本？
我尝试了两种方法，但都失败了：
方法1：
devtools::install_github('ramnathv/rCharts')
Downloading github repo ramnathv/rCharts@master
Error in function (type, msg, asError = TRUE) : couldn't connect to host
方法2 :(手动下载软件包并运行install.packages）
install.packages("~/R/win-library/rCharts-master.zip", repos = NULL)
Warning in install.packages :
package ‘~/R/win-library/rCharts-master.zip’ is not available (for R version 3.1.1)
编辑：我试过了：
library(downloader)
download("https://github.com/ramnathv/rCharts/archive/master.tar.gz", "rCharts.tar.gz")
install.packages("rCharts.tar.gz", repos = NULL, type = "source")
它现在有效！谢谢！
