How did I miss the GrapheR package? The author, Maxime Hervé, published an article about the package [1] in the same issue of the R Journal as we did on googleVis. Yet, it took me a package update notification on CRANbeeries to look into GrapheR in mo...

Testing an R package’s interactive graphs

I’ve been working on an R package, R/qtlcharts, with D3-based interactive graphs for quantitative trait locus mapping experiments. Testing the interactive charts it produces is a bit of a pain.

The Learning R post shows how to grab the crayon colors from the wikipedia page, “List of Crayola crayon colors,” directly in R. Here’s […]
