Yes, and posting to R-help three minutes after posting to R-sig-geo, the 
correct list - raises the question about who's time is more important, 
doesn't it?

What does help.search("read.dbf") tell you? 

(hint: read.dbf() in shapefiles calls read.dbf() in the recommended 
"foreign" package, which is certainly already present in your (unstated) 
Windows binary R 2.4.0 installation.)
