Dear all, This relatively routine analysis has left me frustrated and in a rut. I have a dataset (data1), which I subset in order to remove rows where HabitatDensity="Med". This dataset looks correct when I call it up, however, when I create a table out of the new subset (data2), my table continues to show the "Med" information as 0.
This is a problem because I need a 2x2xK structure for my analysis and
the fourfoldplot routine, and therefore wish to eliminate data where
HabitatDensity="Med".
Simple question (and probably simple answer): How can I delete the
HabitatDensity=="Med" from the dataset or table, so that I be left with
a 2x2xK table.
Thanks for any assistance.
Kind regards,
Scott
