One of the issues several of us have been discussing over the last few months is how to incorporate a mechanism for structured exception handling into R. A prototype of one possible approach is available at http://www.stat.umn.edu/~luke/R/exceptions/simpcond.html It is also available off the developer page, http://developer.R-project.org. The package that implements the prototype requires R 1.3. (It is mostly R code but needs a few hooks that have been added to R 1.3 to allow experimenting with this sort of thing). If you would find this sort of thing useful please give it a try and let us know if you have any comments or suggestions. luke
