安装dplyr给了我较旧的版本

Question

我正在尝试安装最新dplyr版本(版本0.4.1).但是,每次尝试install.packages("dplyr")超过几天都会导致安装0.2版本.

> install.packages("dplyr")
Installing package into ‘C:/Users/Ricky/Documents/R/win-library/3.1’
(as ‘lib’ is unspecified)
trying URL 'http://mran.revolutionanalytics.com/snapshot/2014-10-01/bin/windows/contrib/3.1/dplyr_0.2.zip'
Content type 'application/zip' length 2235535 bytes (2.1 Mb)
opened URL
downloaded 2.1 Mb

有什么步骤我不见了吗？这是Revolution Analytics用户特有的吗？

使用时下面的会话信息.

编辑: .libPaths()添加输出

Answer 1

问题是您正在使用MRAN的一个快照作为您的存储库.这些快照已经到位,以便更容易确保再现性.如果您使用了checkpoint包,则可能已设置此项.

如果您不想这样,则需要更改存储库以不使用快照.例如:

install.packages("dplyr", repos = "http://mran.revolutionanalytics.com")
