#calculate standardized MDS coordinates
dat <- sweep(USArrests,2,colMeans(USArrests))
dat <- sweep(dat,2,sqrt(diag(var(dat))),"/")
loc <- cmdscale(dist(dat))

#plot with no overlap
textplot(loc[,1],loc[,2],rownames(loc))

#scale by urban population size
textplot(loc[,1],loc[,2],rownames(loc),cex=USArrests$UrbanPop/max(USArrests$UrbanPop))

#x limits sets x bounds of plot, and forces all words to be in bounds
textplot(loc[,1],loc[,2],rownames(loc),xlim=c(-3.5,3.5)) 

#compare to text (many states unreadable)
plot(loc[,1],loc[,2],type="n")
text(loc[,1],loc[,2],rownames(loc))
