I think Greg's blog would get more exposure and discussion if it were available as a shiny app. If you click on the "Files" link at the bottom of this wikidot page you will see Greg's R code. This would be loaded into RStudio, which would then "compile" it into a shiny app. Also at the bottom you will also see three csv files the program needs. Versions of those three files on one's computer could be selected using shiny drop-down boxes. It has been a few weeks/months since I read Greg's paper, but there may be one or two other defaults in his algorithm that could be changed with shiny selection widgets. RStudio will host the online app for free.
I've had experience building csv file selection boxes in shiny online apps and have been intending to start this project for some time. But it would be more fun to work on this with other people — and might actually get done that way! Let me know if you're interested by replying to this post. Thanks.
