R help - May 2006 - Until the key pressed: FOR-LOOP-Clustering

Hi All,

These are the code that i used to plot the kmeans clustering.

 DataSetS01022<-rbind(matrix(rnorm(50),ncol=2),
+ matrix(rnorm(50),ncol=2))
> colnames(DataSetS01022) <-c("timeslot","em")
> (cl <-kmeans(DataSetS01022,2))
>plot (DataSetS01022, col=cl$cluster)
> points(cl$centers, col = 1:2, pch = 8, cex=2)
Now, i would like to do *the same process for 5 times*, so that i can view
the clusters in data
have been moving and the center changes with various results.
(Animation-like)

My main concern here, is how to put this in a *loop form* or any other
methods are available?

I tried with:* clarax$clusinfo I thought of doing it to activate Device (1)
& (2)*
**
*Really need anyones help!*
**
*JJ*

Not sure exactly what you're asking, but I'll take a stab at it:
Try adding par(ask=TRUE) before the for() loop.
