Greetings,
Has anyone else noticed a change in the behavior of the under/over/between
arguments in the classInt package?
I utilized those arguments with classInt_0.1-9, but I haven't had any
success with subsequent versions. I read the old and new help guides but
couldn't see a change to the way those arguments must be submitted to the
classIntervals() and findColours() functions. Perhaps I've overlooked a
change?
In the meantime, I have gone back to using classInt_0.1-9. Below is a
reproducible example.
Please let me know if you have any insights that would allow me to use the
under/over/between legend arguments with the most recent version. Thanks.
Regards,
Chris
