summing and combining rows
...'ve read.
My data are structured like this:
Plot SizeClass Stems
12 Class3 1
12 Class4 3
17 Class3 5
17 Class4 2
I simply want to sum the size classes by plot and create a new data
frame with a size class called "Class34" or with the SizeClass variable
removed. I actually do have other size classes that I want to leave
alone, but combine 3 and 4, so if I could figure out how to do this by
creating a new class, that would be preferable.
I've also attached a more detailed sample of data.

So in made a matrix and used
>fisher.test(classtable4).
But then this error occurs:
Fehler in fisher.test(classtable4) : FEXACT error 7.
LDSTP is too small for this problem.
Try increasing the size of the workspace.
Well I...
