I run this:
install.packages('devtools')
library('devtools')
source_gist("https://gist.github.com/hadley/6872663")
I get this:
Error: client error: (403) Forbidden
Why?
I think it is a bug( some regular expression problem), As a workaround :
source_url("https://gist.github.com/hadley/6872663/raw/hi.r")
SHA-1 hash of file is 54f1db27e60bb7e0486d785604909b49e8fef9f9
[1] "Hi from github :)"
