My family and I love boardgames.  We are also on the lookout for new ones that would fit with the ones we already like to play.  So I decided to create a boardgame recommendation website built it using R.  The recommendation engine uses a very simple collaborative filtering algortihm based on correlation scores from other boardgame players collection lists.  The collections are gathered using the API from  It is very much in a beta project phase as I just wanted to get something built to get working. I also wanted another project to build in Shiny.  I really like how easy it is to publish R projects with Shiny. Some of the features include:Ability to enter your own collectionGet recommendation on your collectionAmazon link to buy boardgame that is recommendedIts a work in progress.  There is much to clean up and to make more presentable.  Please take a look and offer comments to help improve the website.

Languages used by data scientists rank highly in this metric. Python is ranked #3 (up from #4 in the June 2016 rankings). R is ranked #14,…

@eddelbuettel’s idea is a good one. (it’s a quick read…jump there and come back). I often wait for a complete example or new package announcement to blog something when a briefly explained snippet might have sufficient utility for many R users. Also, tweets are fleeting and twitter could end up on the island of misfit… Continue reading →
