[R] boxplot of different colors

[Sarah Goslee]

Hi Elaine,

Without a reproducible example it's impossible to say, but I'd take a
hard look at:
table(obs.group)

If that doesn't give you some insight, a small reproducible example
included in your email using dput() would allow us to answer you more
effectively.
