Creating beautiful trees of clusterings with R (+a bonus)

  • Sep 5, 2013 · 6:15 PM
  • This location is shown only to members

Thanks O'Reilly Strata for sponsoring this meeting. We've got pizza and books to give away!

Tal Galili, the founder of R-bloggers (and also a PhD student of statistics), will present his recent work on the package "dendextend" - intended for visualizing and comparing trees of heirarchical clusterings (a.k.a: dendrograms) with R.

We will start by giving motivation from a case study of using R to compare two family-trees, and continue with a step-by-step tutorial of the "dendrogram" objects in R and its manipulation with the "dendextend" package. From this talk you will know how to create, change, visualize, and statistically compare two trees of heirarchical clusterings (with some sprinkles of Rcpp).

A "bonus talk" in this meetup will be the 5-minutes lightining talk Tal gave in the recent useR!2013 conference about how to quickly update R on windows/mac, using the 'installr' package.

• package - github.com/talgalili/dendextend

• package - github.com/talgalili/installr

All levels are welcome and are encouraged to attend, meet and greet. Bring your questions!

    Will the presentations be available online for later viewing?

    I likely won't be able to make it, but am still very interested in learning how to do this.

    Bryan,

    There will not be a recording or anything, but I can certainly post the slides and any other material available. I'll do this after the meeting tonight or tomorrow morning.
