...been updated. While the data have been publicly available for some time now, NMMAPSdata, in addition to being a convenience for R users, assembles all of the city data into one package and contains some utility functions for managing the database. NMMAPSdata can be downloaded from http://www.ihapss.jhsph.edu/data/NMMAPS/R/ The package comes with a vignette which contains an overview of the data and a few example analyses. Comments and suggestions are greatly appreciated. Roger Peng Leah Welty _______________________________________________ R-packages mailing list R-packages at stat.math....

The authors spoke as if this were the ordinary cost of doing business, and pointed to some publications in which the nonconvergence rate was as high or higher. I just don't believe that's right, and if some
