1 Ordination. The vegan package contains all common ordination methods: Principal compo- nent analysis (function rda, or prcomp in the base R), correspondence analysis (cca), detrended correspondence analysis (decorana) and a wrapper for non- metric multidimensional scaling (metaMDS). Functions rda and cca mainly are designed for constrained ordination, and will be discussed later. Dear R-community, dear Jari Oksanen! I use metaMDS (package vegan) to calculate NMDS. In a lot of papers I read that it is recommended to use previous best solutions as a new starting configuration to get better results and to avoid local minima.
