Hello to everybody,

I am new to anova and I have to carry out this simple exercise for a work of mine. I have the following table:

36107(83.37%) 3071 2570(89.55%) 1885 1669(88.54%) \\
9484 (19.53%) 3807 903 (32.72%) 1998 362 (18.12%) \\
1531 (3.1%)   4020 276 (6.87%)  2087 13  (0.62%)  \\
1187 (65.69%) 99   68  (68.69%) 49   32  (65.31%) \\

where each row represents a particular environment (say A, B, C, D) and each couple of columns represents, respectively:

1) the total population of class i

2) the proportion of population of class i belonging to environment j (with j \in \{A, B, C, D\}. Hence, in our table we have three populations (say g1, g2, g3).

I would like to compute the global DF, F test value and p value for the Populations, for the Environments and for their interaction (Populations*Environments).

I have understood that I need function anova2, but I have not figured out how to employ it in this case.

Many thanks for your kind attention and my best regards!

Jason.
