Problem installing with devtools

[audreylk]

I keep getting the following error whenever I try to install methylCIPHER using devtools...

devtools::install_github("MorganLevineLab/methylCIPHER")
Downloading GitHub repo MorganLevineLab/methylCIPHER@master
from URL https://api.github.com/repos/MorganLevineLab/methylCIPHER/zipball/master
Installation failed: 404: Not Found (404)

Is this a "me" issue, or is there a problem on the repo side of things?

Thanks!!
