[R] Error using qda on the spambase training dataset

I am trying to run the code for quadratic discriminant analysis with the
Spambase data set following the code example in the book "R in a Nutshell"
by Joseph Adler (page 443).
The line of code:
> spam.qda <- qda(formula=is_spam~.,
gives me an error:
Error in qda.default(x, grouping, ...)
: rank deficiency in group 1
(There really is a "tilde" after is_spam in the code, only on this
web-page it appears as a hyphen :)
Can someone please tell me why it does not work with me but appears to do
so in the book? I am using R version 2.13.0.
