This data set was previously analysed in:

It gives the (x,y)-coordinates of pyramidal neurons in area 24, layer 2 
of the cingulate cortex. The data are 
taken from a unit square region 
(unit of measurement unknown) in each of 31 subjects, grouped as 
follows:



1. Controls : 12 subjects, cell numbers 1:43; 44:82; 83:148; 149:209; 
210:274; 275:306; 307:412; 413:475; 
476:513; 514:569; 570:615; 616:653



2. Schizoaffectives: 9 subjects, cell numbers 654:689; 690:701;
702:756; 757:768; 769:822; 823:901; 902:962; 
963:1038; 1039:1059



3. Schizophrenics: 10 subjects, cell numbers 1060:1106; 1107:1108; 
1109:1165; 1166:1202; 1203:1218; 1219:1262; 
1263:1303; 1304:1341; 
1342:1388; 1389:1398


To read the data into R, use:
   data<-scan("benes.txt")
   data<-matrix(data,1398,2,byrow=TRUE)

(with the obvious modifcation if the data-file is not stored in the current folder)

NOTE: these data differ slightly from the data used to compute Figures 5.5 to 5.8 in the book
