Where do I get 'httr' for R version 2.15.2

Question

Hi, all. The 'httr' file that CRAN website provides only works on those Rs with versions higher than 3.0. I have a R version 2.15.2 . Where can I get 'httr' for my version of R? Thanks!

May I know what is the correct way to achieve my objective?

Sincerely, Alicia.

You can get the old archives of a package from cran. For httr the archive is at cran.r-project.org/src/contrib/Archive/httr . For projects on github some developers will have tagged releases. httr has the following releases https://github.com/hadley/httr/releases . You can install a package from github using the install_github function from the devtools package.

devtools::install_github("hadley/httr", ref = "httr-0.2")

would install the release tagged 'httr-0.2'
