First line

The text says "... into your curent session." and I believe it was intended to be "... into your cuRRent session." (the uppercase added just for visibility). Notice that I hare reported this before but in the process I introduced another typo.

Table 7.1, example for vector of category raw

The example says CharToRaw("Hello") but I believe it should be charToRaw("Hello"), that is, the command should start with lower case.

3rd paragraph

I configured the "bbdb" DSN for the baseball data using the path shown by the following expression:
system.file("extdata","bb.db", package="nutshell.bbdb")

I loaded the the RODBC package
library(RODBC)
and established the connection using the odbcConnect function:
bbdb <- odbcConnect("bbdb")

But when I tried to get a list of the tables it returned no information:

> sqlTables(bbdb)
[1] TABLE_CAT TABLE_SCHEM TABLE_NAME TABLE_TYPE REMARKS
<0 rows> (or 0-length row.names)

sqlColumns(bbdb,"Allstar")
Error in sqlColumns(bbdb, "Allstar") :
?Allstar?: table not found on channel

second equation

The first equation on the page is for "Pearson correlation statistic" while the paragraph before the second equation suggests that the second equation is "Spearman correlation statistic". It looks to me like these two equations are the same thing. Was the intention here that the second equation should be the "Spearman rank correlation statistic" rs=1-((6∑D²)/(n(n²-1))) or am I missing something?

1st paragraph

Author states "is the difference due to chance or is it likely that these two variables (delivery method and sex) are independent?". Aren't "difference due to chance" and "independent" the same thing in this context?
If so, it should state "or is it likely that these two variables (delivery method and sex) are dependent".

Found in 2010 edition.

Note to the author: great book!
