Of course by entering 'blah' you just get a legend of one value. I guess I
would like to remove the text altogether and put the colored boxes (or circles)
right next to each other. This would form sort of a gradient. So say I needed a
legend for 100 colored values on the plot. The colors are generated by:
colors<- rainbow(100)
How would I make such a legend?
Hi Kevin,
It sounds like you want something like color.legend (plotrix) that draws
a rectangle with as many colors as you like. However 100 colors would
probably require a legend as big as one side of the plot, and you
certainly couldn't get 100 readable labels on it. More like 10.
