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 -- Luke Tierney University of Minnesota Phone: 612-625-7843 School of Statistics Fax: 612-624-8868 313 Ford Hall, 224 Church St. S.E. email: luke@stat.umn.edu Minneapolis, MN 55455 USA WWW: http://www.stat.umn.edu -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
