Thanks Berend, setting lower=c(0,0.01) seems to have solved the problem. I have a dataset with 200+ cropped fields with associated data and wanted to generate each plot in a way that minimized the visual residuals between the green squares and blue circles. I have inserted a resulting plot so you can see how your suggestion has helped me accomplish this end.
