Can R (which as I am quickly discovering is a awsome package) easily perform Two-Stage, Three-Stage, and Seemingly Unrelated Regression? Jeff D.

A more general question that is implicit in many postings to the list is how to find functions in contributed packages on CRAN. One can use the help.search function for this purpose to search installed packages, but I'm unaware of a means for searching the contents of *all* packages. It would be nice to be able to do so.

Most of the errors (aside from worms looking for a Microsoft web server to infect) are attempts to find help files of contributed packages. My current plan is to install as many of these as possible - possibly all of them - by the end of the month. Then you will be able to use my search engine (url above) to look through packages. This should be REALLY powerful when the new version of HdDig becomes available, which will allow searching by phrases. (It is in "beta" now, but I'm waiting.) I will post to this list if and when these changes are made.
