Myself Ph.D. in advanced analytics having 10+ years of experience in developing and delivering and analytical projects using open source R (including in-memory computing), and can deliver your requirement with R, accompanied by a step-by-step word document, what each line or code means.
As, freelancer.com bid does not allow for attaching, cannot showcase my expertise in this area. I am available at freelance chat (click on my name and options) and also at skype "mav_kumar" (Freelancer - Dr. Kumar PM), to understand the details and explain my approach if required in detail.
Waiting for your reply.
Regards,
Dr. Kumar PM.
