2015-12-22 Thread michael.eisenring
Dear R-List members, I have to compare how similar two types of forest (old growth=O) and (young forest=Y) in terms of moth communities are. I sampled moths at 4 O and 4 Y sites. I need to analyse the data using a PERMANOVA approach. But I am having a really hard time to do this in R. I found o
