Hi, I intend to use the BiodiversityR package to perfom community analyses. I will do ordination analyses and diversity comparisons (e.g. accumulation curves, etc.). I have repeated measures of plots and want to control for it when performing analyses. I have not decided yet which analysis I will precisely use, but I am concerned about using the right sample unit. All I can see right now would be to have an 'environmental variable' standing for the plot name... I can't find any mention of 'repeated measures' in the Tree Diversity Analysis book or R documentation provided for the package. Does anyone have references where I could learn more about this? Thanks a lot.
