Hi Charles,
Thanks for answering - you are right about the posting guide (sorry).
In any case, my question wasn't on how to reorder the columns (that is
simple), but on how to choose what order to put them in.
OK, and I see you included a reference, so there is probably more to this
than meets my eye.
But would something as simple as this be good enough??
library(MASS)
hc1 <- hclust(dist(cor(log(iris[, 1:4]))))
parcoord(log(ir)[, hc1$order ], col = 1 + (0:149)%/%50)
or possibly
hc1 <- hclust(dist( abs( cor(log(iris[, 1:4])))))
Chuck
Thanks,
Tal

Hello all,
I am searching for a way in R to re-order variables before presenting them
in a parallel coordinates plot.
So far I didn't find anything within a R related context on how to do
this.
I did find some texts talking about how it should be done in general, here
is such example:

Is there a package or an example of the variable ordering (for parallel
coordinate plot) in R ?
Follow the posting guide
??parallel
library(MASS)
?parcoord
example( parcoord )
See the last line of the example.
HTH,
Chuck
Thanks,
