R 安装sparklyr，ggplot2等包出现如下warning
package ‘＊＊＊＊’ is not available (for R version 3.0.2)
系统环境 ubuntu14.04
上述问题纠结了我很久，尝试过自己安装packages.zip包，出现了版本不对的报错
this R is version 3.0.2, package 'ggplot2' requires R >= 3.1
于是考虑到升级系统，猜测可能是底层依赖以及R的版本过低，于是运行如下命令在我的电脑里生效了，大家如果遇到可以用此方法试下
sudo add-apt-repository ppa:marutter/rrutter
sudo apt-get update
sudo apt-get upgrade
如果出现如下错误：

R语言的报错比较粗糙，有些时候只是说not available，但并没有告诉你到底哪里不匹配，这里应该算是个小bug，但Mac－OS以及win目前还没遇到过
