Dear all,

Sandy Weisberg and I would like to announce version 2.0-0 of the car
package, now on CRAN. We've released this major revision of the package in
anticipation of the publication of An R Companion to Applied Regression,
Second Edition (Sage, in press), co-authored by us, which should be
available before the end of the year.

The new version of the car package has a number of new functions and data
sets, along with many changes to old functions, including a change in naming
conventions, using "camel-case" rather than period-separated names: for
example, av.plots() is now avPlots(). For the time-being, old function
names, such as av.plots(), are available as deprecated aliases. A few
functions from the alr3 package have also been rewritten, renamed, and are
now part of car. The alr3 package will be updated later in the year.
