Answer 1

The pertinent lines:

    > failed for package ‘RCurl’

You need to install libcurl for RCurl (which devtools depends on).

From http://www.omegahat.org/RCurl/FAQ.html, assuming you're on a Linux flavour using apt-get:

sudo apt-get install libcurl4-gnutls-dev

should get you the libraries you need for RCurl.

check your R version. Try to update this. This problem will be solved. I spent one day and go through all the solution. No solution work. Try this solution.
