[R] Selecting / creating unique colours for behavioural / transitional data

[Ross Culloch]

Hi Kingsford,

Thanks for the reply - some of the sets/palettes in the RColorBrewer are
ideal, but the i have is that they only go up to 12 colours, and i need 15
colours (sorry, should have mentioned that)- so i assume the only thing i
can do is create my own palette, but i'm having limited success in trying to
work out how to do this.
