vf {ecodist} | R Documentation |
Fits environmental variables to an ordination configuration.
vf(ord, vars, nperm = 100)
ord |
matrix containing an ordination result with axes as columns. |
vars |
matrix with ancillary variables as columns. |
nperm |
number of permutation for the significance test. If nperm = 0, the test will be omitted. |
Vector fitting finds the maximum correlation of the individual variables with aconfiguration of samples in ordination space.
a matrix with the first n columns containing the scores for every variable in each of the n dimensions of the ordination space. r is the maximum correlation of the variable with the ordination space, and pval is the result of the permutation test.
