Install.packages("ggplot2")安装旧版本(1.0.0)

所以我安装了旧版本的ggplot2与install_version从devtools(0.9.1或东西),看看它是如何工作-在以前安装的版本2.0.0的方式.然后我升级了版本,它令人惊讶地给了我1.0.0版本,而不是当前的2.0.0版本.

现在,当我做一个时,install.packages("ggplot2")我得到相同的1.0.0.还Check for package upgrades..从Rstudio菜单中选择" "项目,它告诉我"所有包都是最新的".

是什么赋予了？是不是ggplot现在2.0.0 的最新版本？这是我的会话信息:

感谢Dirk,我看到发生了什么.看起来像安装RRO包重置我的CRAN存储库.我也可以理解为什么必须这样,尽管我可能会对此发出警告.从这篇博客文章中我看到了如何修复它.http://www.r-bloggers.com/permanently-setting-the-cran-repository/
