Ah, I believe I constructed my *.csv wrong in that I only had 1 observation
within groups whereas I needed at least 2.
Originally I had:
Year Depth Biomass1 Biomass2
1999 10 14.3 14.7
1999 15 14.7 15.6
etc.
but I switched this to:
Year
If I've understood correctly, you have cell sizes of 1. This is not enough.
ANOVA compares within group variance to between group variance, and
your within group variances are zero.
You need more data, or to collapse some cells.

Hello, I'm new to R and have been following many guides including the two-way
anova (http://www.personality-project.org/r/r.anova.html). Using that
walkthrough including the supplied data I do str(data.ex2) and receive the
appropriate types of data as follows:
