Here's a manual solution removing Sepal.Length using NA for vector type and label color:
ggord(ord, iris$Species, vectyp = c(NA, 'solid', 'solid', 'solid'), labcol= c(NA, 'black', 'black', 'black'))
I think a bigger question though is whether or not its misleading to show some vectors and not others. If it's an issue of data overload, I would consider refitting the model with less species (or maybe group by genus?). Perhaps removing those with very low abundance would be a good start as rare species can really skew some multivariate methods.
Hi:
Is it possible to reduce the number of plotted vectors on an ordination plot? I want to make an nmds plot and my vectors (species) are too many, obscuring the graph. Is there a way to define which vectors to plot, e.g. by setting a threshold on the abundance?
