What happened to testthat?

I don't remember having any problems with this, but seemingly suddenly, I can't install any packages because testthat is not there to pass tests. As a catch-22, I can't install testthat either, because it's not there to pass its tests.

R version 3.0.1 (2013-05-16) -- "Good Sport"

Platform: x86_64-pc-linux-gnu (64-bit)

Error in library(testthat) : there is no package called 'testthat'

Is there a way to bypass testing for one install run or otherwise work around this so I can fix my R install?

If you are using linux, you don't have to manually download the package, installing the dependency( in this case 'testthat') via your default manager will also work. I have ubuntu 14.04 and R 3.0.2 

sudo apt-get install r-cran-testthat

After running the above command I was able to finally install swirl.

I live somewhere with poor internet, and I didn't want to download a new version of R and all its dependencies to fix this problem. So you can install an old version of testthat manually: http://cran.r-project.org/src/contrib/Archive/testthat/

On version 3.0.2, testthat version 0.8.1 seems to work. Once you have downloaded the gzip file, do:

R CMD INSTALL testthat_0.8.1.tar.gz

For the record, a full update fixed this, but I don't know why.
