Dear R users
Does anybody know how it may be possible to plot the labels of a ordihull
function separately (in R vegan)? We have studied the bee community in 5
different habitat types. As you see from the code, we use different point types
(pch) and line types (lty). This is only possible if we change the habitat from
character to integer. However, we prefer to show the labels as characters and
not as integers 1-5? Furthermore, does anybody now how to plot the labels at
the border and not in the centroid of the polygon (due to overlapping polygons
it is not easy to assign them to the right polygon)?
Many thanks
Sibylle
### NMDS code ####
example_NMDS=metaMDS(community_matrix, # Our community-by-species matrix
distance = "bray", k=2) # The number of reduced dimensions
stressplot(example_NMDS)
ordiplot (example_NMDS, display = 'species', type = 'n', xlim=c(-0.5,0.5),
ylim=c(-0.7,0.7))
HabTyp<-as.integer(S1$H_Aggregat1) # 5 different habitats.
points (example_NMDS, col="black", pch = HabTyp)
for (i in unique (HabTyp)) ordihull (example_NMDS, groups = HabTyp, show.group
= i, draw = 'polygon', label=T, cex=1.5, lty=i)
