[R-sig-Geo] function classIntervals {classInt}: arguments over/under/between

[Pascal Oettli]

Hi,

 From the help file:
"From version 0.1-11, the default representation has been changed to use 
cutlabels=TRUE, and representation within intervals has been corrected, 
thanks to Richard Dunlap."

You need to use cutlabels=FALSE

print(classIntervals(jenks71$jenks71, n = 5, style = "equal"), cutlabels 
= FALSE, between = "-", under = "<", over = ">")

Regards,
Pascal
