I tried using points() to add values to my plot, but only the original plot works and the function doesn't do anything or raise any errors. I have the functions walk.effectiveleg.length and walk.effectivehip.height defined previously and they can be plotted just fine on their own, but I can't figure out how to plot them together. Does anyone know what could be going on?
I have used points in other plots in the same notebook and it runs just fine, just not on this one.
plot(walk.hip[,1], walk.effectivehip.height, col="blue")
points(walk.hip[,1], walk.effectiveleg.length, col="red")
