In this tutorial you will learn: what is a heatmap how to create a clean, highly customizable heatmap using heatmap.2 in the gplots package in R how to remove samples with poor output (not very many sequences) how to rearrange your samples by a metadata category how to make a color coded bar above the heatmap

Drawing a scatterplot with the marginal boxplots (or marginal histograms or marginal density plots) has always been a bit tricky (well for me anyway). The approach I take here is, first, to draw the three separate plots using ggplot2:

We've mentioned before how you can use R to design 3-D objects. Now, thanks to the latest version of the rgl package, you can produce real-world 3-D objects with R as well. The rgl package has long made it possible to create virtual 3-D objects in R, and export them as animations like this: But now, package author Duncan...
