Dear R Users,
I'm able to display a legend using the following code:
> legend("topright", c("Simulation", "Observation"), fill=2:3, bty="n")
However, this causes the legend to be positioned too close to the bars in my
barplot. I'd like to move the legend up slightly. I have been trying to
determine the necessary values by trial and error to do this manually (by
entering a coordinate) - however, I can't seem to get the legend to display! I
must be off-limits, although I have tried a range of values.
I can do a temporary fix by doing locator(1), but I'd ideally like to learn how
to determine the range of coordinate values 'available' within the graphics
console in order to state the x and y values for legend positioning in the
legend command. Is there an easy way to do this?
Thanks,
Steve
