Error installing R package atSNP - r

Question

I am trying to install an R package atSNP from https://github.com/chandlerzuo/atSNP. According to the documentation, this is how it is installed:
> library(devtools)
> install_github("chandlerzuo/atSNP")
But I get the following error:
Downloading github repo chandlerzuo/atSNP#master

As you can see, I have installed & attached both packages GenomicRanges & motifStack and still the installation message says they are not available. I have tried uninstalling & reinstalling both the packages but I still get the same error. Any suggestions will be appreciated.

You can download the source package from the github website and install it. This gives no error on my Mac. In the terminal, type
git clone git://github.com/chandlerzuo/atSNP.git
R CMD INSTALL atSNP
