It is a really wonderful example, describing over 3 1/2 pages how S3 classes can be lightweight and effective for the right problem size.
The book is from 2000, which is when I bought my copy. I once heard rumours of a 2nd edition but that was years ago, and never happend.
Sometimes the classics, e.g. S Programming by Venables & Ripley, give the best examples. Great practical breakdown of an S3 class without relying on decomposing the `lm` object (and, that's quite a rabbit hole). Thanks @eddelbuettel for the heads up.

R 3.5.0 is out, and Debian packages have been uploaded to "experimental".
We will get a binary transition going for the required package rebuilds.

R/Finance 2018 registration has been open for a few days; see the blog post by @joshua_ulrich at the link below.
The is a serious shortage of hotel rooms due to a large medical conference. So think AirBnB, UIC dorms, or other alternatives! I'll auction off our guest bedroom :)

A current 'beta' (from last eve, r74578) is in @Debian "experimental" release.
Please test.
A reminder that #rstats 3.5.0 is currently in beta and enters Code Freeze on Monday. I.e., bugs not discovered within this week WILL appear in the released version. So do test it if you want to have an influence on it.

Extending R: my talk at tonight's Chicago R User Group meeting; slides now at goo.gl/dZnpyV
This was at the new home @jeffersontap1 -- my thanks to the ChiRUG for settings this up. Folks were either excessively kind, or maybe the talk went well indeed.

I find it strangely satisfying to click "I don't like this ad" for every ad Twitter puts in my feed. I like to imagine that there's a finite number of ads in the Universe, and after I have expressed my displeasure at the lot, I'll live an ad-free and joyful life.

As @joshua_ulrich would say: "lightweight is the right weight".
Keep your dependencies down, keep it simple (enough) and make sure it works.
