## Collaborative Filtering by R
 This post impliments user-based collaborative filtering using R. Idea comes from [the blog post by Salem](http://www.salemmarafi.com/code/collaborative-filtering-r/). I vectorise the code thus significantly reducing the runtime. Visit his blog for more information. (http://www.salemmarafi.com/)
