I finished the R course offered from Johns Hopkins when it was first offered a few years back. I was doing my MS at the time and it gave me an edge over students who were just beginning the fundamentals of R. I could do a more in-depth analysis for my project, so it certainly helped me. It wasn't paid. Would I have paid for it - for what I learned and how R is a big part of the work I do, I want to say 'yes'. But I think you need to have a clear understanding of what outcomes you expect before committing to a paid course.
