Hello.

I am for the first time trying to make a Variance Partitioning analysis with R, and I am new to both.

I want to understand how is the variance of several trees functional traits (leaf area, specific leaf area, wood density...) partitioned by size (height and stem diameter of the plant) and phylogeny (family and species).

I am using the varpart() function of the vegan package in R. I would like to nest the philogeny levels (species into family), to see if there is a difference in the results if the phylogenetic factors are not inserted independently in the model.

Is this possible, and how can I code it?

Thank you!
