	Ah-ha.  Oh me of little faith.  I have been hanging around (in
	my current work environment) with too many SPSS users, and the
	*.sav extension seems to be the standard for SPSS data files.
	Whence my corrupted thinking.

	Hmmm.  When I opened it with Excel on the Mac I got a spread
	sheet with 503 rows --- the first row being the column names,
	so there were really 502 rows.

	And 502 rows was what I got when I saved the *.xls file as a
	*.csv file and then read that in.

	Also, when I followed Phil Spector's excellent advice and
	loaded prostate.sav from the website, using load(), I ***again***
	got a data frame of 502 rows.  This data frame is (modulo some
	classes and attributes) identical with what I got from reading
	from the *.csv file.

	Where have the other four rows gone?  Ravi Varadhan also observed
	this phenomenon.
