Computation of the Distance Matrix from a Statistical Triplet
Description
computes for a statistical triplet a distance matrix.
Usage
dist.dudi(dudi, amongrow = TRUE)
Arguments
dudi
a duality diagram, object of class dudi
amongrow
a logical value computing the distance if TRUE, between rows, if FALSE between columns.
Value
an object of class dist

Examples
data (meaudret)
pca1 <- dudi.pca(meaudret$env, scan = FALSE)
sum((dist(scalewt(meaudret$env)) - dist.dudi(pca1))^2)
#[1] 4.045e-29 the same thing
