What I most like about this text is that it is about the R language and not about the domain in which R has found the greatest application. I find R perfectly suitable for basic, pre-statistical signal processing for example. Far better than Matlab at a fundamental level. In fact, about anything that Matlab is good for R is better. Except of course for the evolution of the surrounding packages. All the prior tutorials and courses I've seen presume and utilize a background in the domain of statistics and a require a fairly strong one at that. I strongly believe R should be sprung free of that encumbrance so as to find a wider audience and this is a really good effort in that direction.
