using ifelse with surprising results
Thanks for the gracious assistance in advance
I'm working on a non-metric scaling problem and am calculating the distance
for input to isoMDS
Here is the code
library(MASS)
vegdata <- tapply(Percent, list(PRIMARY_VE, MASTERID), sum)
x.mat <- matrix(x, nrow=40, ncol=2750, byrow=TRUE, dimnames =
c(dimnames(x)[1], dimnames(x)[2]))
vegdata.dd <- dist(x)
vegdata.dd <- ifelse(vegdata.dd==NA, 0.01, x.dd)
vegdata.dd
Everything works as expected until I try to repla...

envfit vector labels with ordiplot3d
Hi R experts,
I'm looking for some help with plotting vectors from envfit in vegan, onto a
3d plot using ordiplot3d. So far I have
data.mds <- metaMDS(data, k=3,trace = FALSE)
vect_data<-envfit(data.mds,vegdata[,3:21],choices=1:3,permu=9999)
ordiplot3d(data.mds,envfit=vect_data)
ordixyplot(data.mds,pch=pts,envfit=vect_data)
(my data's not really called data, I thought it might be easier to
communicate this way)
These display the vectors as arrows, but what I would really like is for the
arrows to be...
