add.csc.metaMDS: Adds circle of significant contribution onto ordination...

In zdealveindy/conford: Confidence intervals for environmental variables in diagrams of unconstrained ordination

Description

Adds circle of significant contribution onto ordination diagram

Usage

add.csc.metaMDS(ord, x, arrow.mul, at = c(0, 0), add = T, choices = c(1,
  2), ci = 0.95, ...)

Examples

library (weimea)
library (vegan)
data (vltava)
env <- vltava$env$pH
#add randomly generated variables
 set.seed (1234)
 nmds <- metaMDS (vltava$spe)
env <- matrix (rnorm (8*97), ncol = 8, dimnames = list (NULL, names (vltava$env)[c(1:6, 11:12)]))
ordiplot (nmds, display = 'si')
for (gr in 1:4) ordiellipse (nmds, groups = vltava$group$GROUP, show.groups = gr, col = gr)
ef <- envfit (nmds, env)
add.csc.metaMDS (ord = nmds, x = ef, fg = 'grey', lwd = 2, ci = 0.95)
plot (ef)
