Multidimensional Scaling Plot of Proximity matrix from randomForest
Plot the scaling coordinates of the proximity matrix from randomForest.
Usage
MDSplot(rf, fac, k=2, palette=NULL, pch=20, ...)
Arguments
 rf
 an object of class
randomForest
that contains theproximity
component.  fac
 a factor that was used as response to train
rf
.  k
 number of dimensions for the scaling coordinates.
 palette
 colors to use to distinguish the classes; length must be the equal to the number of levels.
 pch
 plotting symbols to use.
 ...
 other graphical parameters.
Value

The output of
cmdscale
on 1  rf$proximity
is
returned invisibly.
Note
If k > 2
, pairs
is used to produce the
scatterplot matrix of the coordinates.

Examples
library(randomForest)
set.seed(1)
data(iris)
iris.rf < randomForest(Species ~ ., iris, proximity=TRUE,
keep.forest=FALSE)
MDSplot(iris.rf, iris$Species)
## Using different symbols for the classes:
MDSplot(iris.rf, iris$Species, palette=rep(1, 3), pch=as.numeric(iris$Species))
