I have a dataset of absolute counts and relative abundance obtained from qPCR experiments. I'm interested in calculating the Bray-Curtis dissimilarity to analyze the community structure across different samples.
I plan to use the vegdist function from the vegan package in R.
My main question is:
Can I use relative abundance data directly with vegdist, or do I take the absolute counts abundances to calculate Bray-Curtis dissimilarity?
I'm particularly interested in understanding if there are any pitfalls or considerations I should be aware of when using relative abundance data for this type of analysis. Any insights or recommendations would be greatly appreciated!
