Hi Greg,
I think what you want is:
mtext (side=4, "median", col="firebrick4", at=median(walk_seconds))
"adj" defaults to 0.5 and is usually okay. It looks to me as though
mtext has taken your _character_ strings as non-numeric and then tried
to work something out with par("las"). Experts more familiar with the
underlying code may be able to provide a more elegant answer, but mine
is above.
