RGL and Shiny

So I love interactive graphics. I also enjoy 3D graphics, when they are necessary, and RGL suites me pretty well for them.

I recently forked a github repo (, and just made a quick working example of how to make a 3D scatterplot with options of changing data sets, and taking certain types of points out (WM – white matter, GM – gray matter). Try it out here:

Hopefully in the future I can get the camera angles and matrix rotation to stay fixed when adding/deleting points.

Edit: If you clone the repository (using git clone), load up R,
library(shiny), and setwd into the repo directory, and just run
runApp() in R, you should see This screen

Social Network Capability for Conference Apps

Over the past year I went to the Society for Neuroscience (SfN) conference.  If you have never been, it’s a sight (here is a link to the attendance until 2009 – where they had over 30000 in attendance).  Also, the poster session is enormous and a labyrinth if you don’t have a plan.  One good thing was that they had an app to help organize your schedule.  

My question is: why not have the ranking of those that put a poster/session on their schedule for new researchers to see the “hot topics”?  Also, the ability to follow who is going to what poster/session may help you see friends/colleagues or follow someone whose views you respect on the topics?

Obviously it’s easier to ask why they’re not there than to help implement it, but I think these would be the future of conferences, especially large ones.
