[R] How to make a scatter plot

[JohnDee]

Birth order is a factor.  You can't have a fractional birth order - e.g.
ORDER = 1.5 makes no sense.  You are either first, second, third, etc. 
"Order" in your data can only take two unique values, and thus anything
plotted against birth order is only going to vary along a vertical line
above permitted values of birth order.
