GrapheR: A GUI for base graphics in R

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.

Two more points about crayon colors

If you want to use crayon colors in R but you don’t want to rely on my R/broman package, you can just grab the code. Copy the relevant lines from the R/brocolors.R file: I spent a bit of time thinking about how best to sort the colors in a meaningful way, for the plot_crayons() function. […]
