I\'m trying to install a package via devtools::install_github for the first time
devtools::install_github
l@np350v5c:~$ R --vanilla > library(devtools) Attaching pac
Actually, I had the same issue and after installing RCurl it worked.
In order to install RCurl in ubuntu, write the following in your terminal:
sudo apt-get install libcurl4-openssl-dev
Then in R:
install.packages('RCurl')
And that's it!
