Hello, I had recently contacted you via twitter. https://twitter.com/serdarbalci/status/948321094448140288
For Mac High Sierra when I download the package and extract the RKward does not start and gives error. Probably it is due to that package does not have R in it. However when I use command line tools and Macports I was able to install it. Thank you ----- Dr. Serdar BALCI ---------------------------------------------------
