While reading Chapter 11 Page 168. I found a minor error: con <- dbConnect("SQLite", dbname=system.file("extdata", "bb.db", package = "nutshell")). I couldn't establish the connection with that line. What I did was the following:
con <- dbConnect("SQLite", dbname = system.file("extdata", "bb.db", package = "nutshell.bbdb")).

Please let me know the proper channel to submit my suggestions in case I found others. Again thank you very much for this great book.

first line of code block at bottom

if the file is .pdf, the function should be pdf(),
if the file is .png, the function should be png()

It reads like this in the printed version:
png("~/Documents/book/current/figs/multiplefigs.1.pdf",

Note from the Author or Editor:
Yes, this is correct. It's better to match the command to the file type.

Medicare Data in "R in a Nutshell, 2nd edition" p.333: according to the author the Medicare Data is included in the R-package "nutshell". I couldn't find it there. Maybe it exist in "nutshell" unter another name? Is it included or should it be downloaded and attached manually from the website?

Note from the Author or Editor:
Please see the previous errata; I have submitted a revised nutshell package to CRAN and hope that it will be available for download soon.

Box entitled 'Medicare data'

The box says that the data frames to be used are contained within the 'nutshell' package
but trying the very first 'data' command listed on page 334 gives an error saying that
'outcome.of.care.measures.national' doesn't exist.

Sure enough when we look at the manual pdf associated with the 'nutshell' package on cran
we see that it was last updated on Jan 24'th of this year, and that the data.frames used
in this chapter are not listed in the index. I thought then that there might be a 'nutshell2'
library available but it didn't show up in a search.

This is very disappointing. I got this book today because I was particularly interested
in using R's graphics abilities and the *very first* example I try fails. Maybe I got unlucky
and everything else will work perfectly, but it leaves a bad taste in the mouth.

Will the update library be available soon ? Surely it should have been available at the
time of publication ?

Note from the Author or Editor:
I've been having some trouble getting the updated nutshell packages posted on CRAN. (CRAN changed their rules and have imposed a limit on package sizes.)

To deal with the problem, I've broken the nutshell package into three parts. Try downloading again soon (after 12/5/2012).
