Dear friends, we have sampled a taxonomic group in 40 different sites. The data set is abundance-based without any info on species richness. What is the best statistical approach to cluster the sampling sites based on the abundance?
Csn be done done , provided clusters are based distincive differences in datset...could be evident from level of significance..
I think that it IS in function of what you want to do like analysis.
If you just want to grouped these 40 sites bases on their abondance, you Can make use cluster ING method
Yes, you can cluster your site abundance data. Use the kmeans() function in base R. In the function, you'll need to select the number of clusters (attribute is called "centers") which is a bit of a subjective exercise. Google "methods to determining optimal number of clusters" and you'll find many options.
Yes, you can cluster according to abundance, but species richness is really required for meaningful conclusions
