[R] add a color band

[Alaios]

Hi all,
I would like to ask your help to add a color band (Ι am not sure regarding the 
right term, this color band at the right of the plot "describing" values with 
their corresponding color. 

For now I have only this code



test<-matrix(data=runif(10000),nrow=100)
plot(test,axes="FALSE")

axis(1,at=c(0,1),labels=c("a","b")) # 

but  I would like to add at the right  side the color legend.

How can I do that in R?

I would like to thank you in advance for your help

R.
Alex
