Installing dplyr gives me older version

Question

I am trying to install the latest dplyr (version 0.4.1) . But every attempt of install.packages("dplyr") over several different days result in version 0.2 installed.

> 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

Is there any step I'm missing? Is this peculiar to Revolution Analytics user?

Answer 1

The issue is that you are using one of the snapshots of MRAN as your repository. These snapshots are put in place to make it easier to ensure reproducibility. this was probably set if you made use of the checkpoint package.

If you don't want this then you need to change your repository to not use the snapshot. For example:

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