Subject: MASS: isoMDS drops names of points in R-2.1.0 (PR#7786)

Submission from: (NULL) (130.231.102.145)
isoMDS (MASS) drops names of points. The reason seems to be that R-2.1.0
abandoned names.dist that isoMDS uses to get the Labels attribute of dist
object:
points <- matrix(tmp$y, , k)
rn <- if (is.matrix(d))
rownames(d)
else names(d) # This does not work any longer
dimnames(points) <- list(rn, NULL)
list(points = points, stress = tmp$val)
The solution is obvious but not very elegant.
