There is a new package in the devel-section of CRAN called 'strucchange' providing functions for testing on structural change in linear regression relationships. It features tests/methods from the generalized fluctuation test framework as well as from the F test (Chow test) framework. This includes methods to fit, plot and test fluctuation processes (e.g., CUSUM, MOSUM, recursive/moving estimates) and F statistics, respectively. Furthermore it is possible to monitor incoming data online. It only works with the current development version of R (forthcoming 1.3.x).
