Segmented linear regression with breakpoint locations as parameters is NON-linear regression. R^2 for nonlinear regression -- and certainly R^2 for individual segments in segmented regression-- makes no (or at best very little) sense. For why this is so, post on a statistics list like stats.stackexchange.com or consult a local statistical resource. These are not R issues and so are offtopic here.
