sedum.ts function

A data frame with 24 observations on the following 3 variables.
  <dl>
    <dt><code>exchange</code></dt><dd>CO$_2$ exchange, measured as: [change in CO$_2$ concentration (g/mg)]/ plant fresh mass (g).  Thus units are 1/mg.  
    Positive values indicate net CO$_2$ uptake while negative values indicate net CO2 output. </dd> <dt><code>time</code></dt><dd>A numeric vector indicating two hour intervals</dd> <dt><code>treatment</code></dt><dd><code>Dry</code> = water withheld for several week, <code>Wet</code> = plant well watered.</dd> </dl>
