Montana State University published on its web a section containing some extracts relating to the fundamental topics of their course Analysis of Ecological Communities.
This is a real laboratory that introduce the analysts to the deployment of R , and covers all the main analysis applied to this type of study (consider, for example, detrended Correspondence Analysis (DCA) and all instruments derived from GIS). There is a series of example data files, so as structured data files Beauty consulting traditionally used for species and plant ecological communities.
This guide allows those who are already familiar with user of R, to achieve the highest quality and - most importantly - how to apply these techniques in their research.
