PubChem 446220 = Yeyo

I just updated my R package, CTSgetR, for biological database translation using the Chemical Translation Service (CTS). While making code examples I came across some humorous chemical name synonyms for the molecule referenced in PubChem  as CID = 446220. Below are a few examples, can you guess what this is? Badrock, Bazooka, Bernice, Bernies, Blast, Blizzard, Bouncing Powder, Bump, Burese,

Multivariate Data Analysis and  Visualization Through Network Mapping

Recently I had the pleasure of speaking about one of my favorite topics, Network Mapping. This is a continuation of a general theme I’ve previously discussed and involves the merger of statistical and multivariate data analysis results with a network. Over the past year I’ve been working on two major tools, DeviumWeb and MetaMapR, which
