x

output from nmds()

dims

Examples

# Example of multivariate analysis using built-in iris dataset
data(iris)
iris.md <- distance(iris[,1:4], "mahal")

# Minimum-stress 2-dimensional nonmetric multidimensional scaling configuration
iris.nmds <- nmds(iris.md)
iris.nmin <- nmds.min(iris.nmds)

# Plot NMDS result with symbols denoting species
plot(iris.nmin, pch=as.numeric(iris[,5]))
