Dear R users,

there are new versions of the following packages on CRAN:
  o lmtest 0.9-0
  o strucchange 0.9-4
  o ineq 0.2-1

Changes/fixes in "lmtest":
There have been several bug fixes and the interfaces to all functions
have been improved such that their use is much more flexible.
Furthermore we have added:
  - p values for the Durbin-Watson test
  - studentized version of the Breusch-Pagan test
  - flexible specification of the alternative hypothesis of the RESET
  - simulated p values for the Harrison-McCabe test
  - data sets with examples

Changes/fixes in "strucchange":
Besides a few minor changes and improvements there is a new fixed
version of the function Fstats(), which provides also computation of F
statistics based on
heteroskedasticity-consistent covariance estimation.

Changes/fixes in "ineq":
The empirical and theoretical Lorenz curves have now their own classes
plot- and lines-method. A data set with examples has been added and a
few bugs were fixed.
