I don't mean to pick on you in particular, or on the authors of "An introduction to R", but I really don't see how anyone in good conscience can recommend this to a new user of R. I think it does a great job of covering the basics, and is probably a good read after you've been using R for a year or so, but in goes into a lot of depth into things that you really don't need to know for doing practical, day-to-day data analysis.

For example, you don't find out how to actually load data into R until page 30, while you get 3 page on the mode and length of objects at page 12. Do we really need to know that an empty (zero length) vector still has a mode?

These comments are based on my experience teaching R to undergrad stat majors, and so may not apply to your audience. If you teach R in the same order as "an introduction to R" it takes you about 4 weeks before you can actually do anything useful with R, by which time the students are bored to tears. If you start with getting data into R and displaying the data with graphics, you can do useful things very quickly, providing interest and motivation, and then you can gradually introduce a more rigourous description of the components as needed.
