Dear R-Help, I've never had any trouble importing data into R until I had to import an .sdd file for a class. The file can be found here: http://www.math.umt.edu/steele/Math%20549/Farms.sdd. It begins with the line "## Dump S Version 4 Dump ##". I first attempted read.S which issued the message "not an S object". I then checked the Import/Export manual which seemed to indicate that data.restore might do the trick. Alas, it seems that function is trying to interpret the name of the data frame as an S mode or some such thing.
Searched the archives (courtesy of Dr. Baron) and found this from Dr. Ripley: ".sdd files from S-PLUS 6.0 are S4 dumps, and will not work." This was written in 2002, is it still accurate? Right now my only obvious course of action is to get on a machine that has S+, read in this file and dump it in a more useful format. Are their others? Thanks so much, John P.S. I've been an R user for 4 years now and a subscriber to this list for almost that long. I'd just like to say an enormous thanks to everyone who contributes to the R project in some way. R is the most impressive realization of the free software movement I've ever seen. Particular thanks to the R core, those who publish the journal, and the authors of excellent and too-numerous-to-mention books on R and S.
