[R] Partial least square regression and the effect of sampling site

[Claude Leroux]

Hi,

I am trying to use pls regression to find links between some environmnental variables and the biomass of a marine snail species. I am not an expert with this type of analysis. I sampled both the species' biomass and the environmental variables on 3 transects in 6 different sites. I would like to know how to include the effect of the site in my plsr analysis.

Thank you!
