Hi, Greetings from Nepal. I am using R version 3.1.3 (2015-03-09) -- "Smooth Sidewalk" and vegan 2.2-1 I have been using and teaching R to my students some years. I am more used to with simple vegetation data sets. Now I am facing difficulties to handle with temporal scale, site wise variation data. One of my colleagues had fish abundance and water chemistry data of five sites for 4 years each site samled monthly. Data with 5 sites x 4 years x 12 months. I am searching such kind of data and analysis in vegan, but yet could not get. If any of this list have any idea please with example where I can look please provide me link I will be happy to search and learn it. Thank you in advance.
