can
someone please make suggestions for improvement
Perhaps dist.r does not have row.names(dist.r) nor colnames(dist.r)?
We cannot know since we do not have dist.r.

#here is the command
loc_mds<- cmdscale(dist.r, k = 7, eig = TRUE)
loc_mds$eig
sum(abs(loc_mds$eig[1:2]))/sum(abs(loc_mds$eig))
sum((loc_mds$eig[1:2])^2)/sum((loc_mds$eig)^2)
x<-loc_mds$points[,1]
y<-loc_mds$points[,2]
plot(x, y, xlab="Coordinate 1",
ylab="Coordinate 2",
main="Metric MDS", type="n")
text(x, y, labels = row.names(dist.r), cex=.7)#the same as the last code
text(x, y, labels = colnames(dist.r))# I am not getting the drawing why?
With Kind regards
