R - devtools Github install fails

Question

Trying to use Hadleys devtools package I am getting a certification error:

install_github(\"devtools\")
Installing github repo(s) devtools/master from hadley         


        

Answer 1

Try

$ git clone git://github.com/hadley/devtools.git
$ R CMD build devtools
$ R CMD install devtools_1.2.99.tar.gz

or just

$ git clone git://github.com/hadley/devtools.git
$ R CMD install devtools

both worked for me on Ubuntu 12.04. Someone else can weigh in on whether there's any difference in building first then installing from tarball or not. I would guess no, but I have no idea

edit: trying this on os X
