Code records with both < and > values #1

There are some records with results coded as > xxx and < yyyy.

How should we code this?

I hadn't run into this before, What about adding columns indicating whether the observations are censored? "R.Cen" for right censored observations (>xxx) and "L.Cen" for left censored (<XXX). The columns could take a value of 0 or 1.
I'm making progress with Git. Things work as expected from my home computer, but not on my EPA computer. I suspect there may be issues write privleges. I'll work with Ann this week to resolve. Talk to you tomorrow.
