do a variation partioning using vegan package in r

Variation partitioning is a method used in ecological data analysis to partition the variation in a response variable into different explanatory variables. In R, the vegan package can be used to perform variation partitioning analysis. Here are the steps to do variation partitioning using vegan:

  1. Load the vegan package and your ecological data set.
main.r
library(vegan)
data(ecomor)
28 chars
3 lines
  1. Prepare your explanatory variables, which can be environmental or spatial variables.
main.r
env <- ecomor$env # environmental variables
sp <- ecomor$dist # spatial variables
82 chars
3 lines
  1. Use the varpart function to do the variation partitioning analysis.
main.r
vp <- varpart(ecomor$taxa~env+sp)
vp
37 chars
3 lines

The varpart function takes a formula as input, with the response variable (ecomor$taxa) on the left-hand side and the explanatory variables (env and sp) on the right-hand side. The output of varpart provides the portion of variation explained by each explanatory variable and the shared variation between them.

  1. Visualize the variation partitioning results.
main.r
plot(vp)
9 chars
2 lines

This will create a Venn diagram that shows the unique and shared variation explained by each explanatory variable.

That's it! You have successfully performed variation partitioning using the vegan package in R.
