It's alleged that the number of people donating zero is large, and more generally I would expect people to round off their donation amounts when reporting. Ages are clearly also quantized. So there may be lots of points on top of one another. Is it easy to jitter them in the plot, or something like that, to avoid this source of visual confusion?
Apply
jitter()inside ofqplot. Also, transparency:qplot(jitter(Age), jitter(CharityLog,a=0.1), color=EffectiveAltruism, data=survey,alpha=I(0.5))Default
jitter()worked great onAge, but was negligible onCharityLog.
