Anne:
Perhaps this example will help.
I have data (several dozen observations at each condition) for different
R=stress.ratio. The stress.ratios are:
> stress.ratio
[1] 0.1 0.1 0.1 0.2 0.3 0.5 0.6 0.7 0.8 0.9 0.9 0.9 0.9 0.9 0.9
You will notice multiple datasets for R=0.1 and R=0.9.
I assigned colors to each stress.ratio, such that
R.color
[1] "black" "black" "black" "red" "orange" "gray"
"green" "light blue" "blue" "dark blue"
[11] "dark blue" "dark blue" "dark blue" "dark blue" "dark blue"
Then I plotted the legend on my plot this way:
legend(x.coordinate, y.coordinate, unique(stress.ratio),
col=unique(R.color), pch=15, cex=0.8)
Best wishes.
