A new version of the quantile regression package (quantreg 3.09) is now available on CRAN. The new features include: 1. a new fitting method "fnc" for rq() which allow the call to specify linear inequality constraints on the coefficients. 2. an anova() function for rq objects that implements several F-like tests for quantile regression models at a given quantile, and other F-like tests for tests of linear restrictions on coefficients of rq() fits for several quantiles, e.g. tests of equality of slopes across quantile fits. 3. some new plotting routines of the sort appearing in my recent JASA paper with Olga Geling on survival models for the Carey, et al medfly experiment data.
