[R] Simple Question: adding points to a boxplot

[Farley, Robert]

Sorry to keep bothering you all.  Phil's easy fix got my code working and I have my graphic.

Just for my education: Is there a SIMPLE way to verify/ensure that the ordering of the data is the same in both dataframes?  Is this done within the plotting routines, or is it usually as a data checking process before data analysis?


==============================================
boxplot(ObsRpdData)
points(1:length(EstRpdData),EstRpdData, pch=16, col="red)
===============================================

Whoo-hoo, I get the points!

Thanks!

I guess I was over-thinking it.  :-)

Robert -
    What happens when you try

points(1:length(Est1),Est1, pch=23, col="red")

I THINK I'm failing because I need to decompose my estimated dataframe into two vectors.  I can't seem to figure out how to do that properly, or if I'm suffering from a different misunderstanding....
