Dave,

   I've seen the cenros warning when there are > 80% censored data, and now
understand that I don't see the same warning with cenboxplot. Knowing now
that I need at least 2 uncensored observations answers my question; some of
the constituents have only a single uncensored value. Others have none, and
I knew those could not be analyzed or plotted.

   Most certainly does!

Thanks very much,
