Based on this post, Amazon now had decided to bundle R with Amazon Linux AMI

R 2.15: Also coming from your requests, we have added the R language to the Amazon Linux AMI. We are here to serve your statistical analysis needs! Simply yum install R and off you go.
ps- back to work. sorry for the delayed posts . I am working on book 2 for Springer- “R for Cloud Computing” . If you have any case studies of R on Amazon,Google, Oracle or Azure clouds please let me know.
pps- With 48 mb, is R too big to bundle in the many default Linux distros . Thoughts?
