I had previously installed haven from CRAN, but then installed haven from Github using

devtools::install_github("hadley/haven")

and wanted to check whether I got the correct version. sessionInfo() says, among other things:

other attached packages:
[1] haven_0.2.0

However, this is also the version from CRAN. How can I be sure this is the current version from Github?

    Did you `library(haven)`? It shouldn't show up there until you do. After you do, the latest installed version will show up. – David Arenburg Apr 11 '15 at 18:24
  • @DavidArenburg I see. However, my question was merely how do I distinguish between CRAN and Github. If I knew the Github version number, this was correct. Since I don't, daroczig's answer helps. – FooBar Apr 11 '15 at 18:26

    As an aside, if folks used (local or GitHub) repos (which eg [drat](http://dirk.eddelbuettel.com/code/drat.html) makes easy) then version number comparison would still work. This is a devtools / GitHub issues of not using proper R tools for tracking packages. – Dirk Eddelbuettel Apr 11 '15 at 18:26

    @FooBar: But you [do know the GH version number](https://github.com/hadley/haven/blob/master/DESCRIPTION#L2). – Dirk Eddelbuettel Apr 11 '15 at 18:27

Use session_info from the devtools package:
