[R] barplots with no lines around each bar

[Doug Beare]

Hi,
I want to do a barplot with no black lines drawn around each bar and no 
space between each bar. I can do the nospace bit but keep getting black
line around each bar no matter what I try.
Ie. for a red bar I want a red border, for a yellow bar a yellow border 
and so on. I've tried everything I can think of but no luck. Any 
suggestions? At the moment I'm using R 5.1 under Redhat Linux 8.
Regards,
Doug Beare.
