Someone was asking how to do a 16 category piechart in OpenOffice Calc and it appears that it can not be done (which we, probably, should be happy about) but I thought that I'd try it in ggplot2.
It works but I then thought I'd like to make the colours more distinctive but fro some reason I don't seem to be able to use manually assigned colours. Can anyone suggest where I'm going wrong?
