R help - Feb 2003 - ClustPlots part 2

Being more specific regarding the plots...
according to the docs the plot command is
smart enough to know which kind of plot is required based on the object passed
as parameter.
So I want to make several plots,from different objects, save each one in a JPEG
or PNG but
each I try that the 1st plot stops the command line window asking what type of
plot do I want to see.
How can I disable that interactiveness ?
I am using a R file as source I was hoping to end up with several PNG or JPG in
directory...

Thanks in advance
Mark Marques

I am using the library(cluster), and (mva)
Clustering function clara()

sometihng like this:

cdata <- clara(vdata,6)
plot(cdata)
savePlot(filename="c:\\clara1",type=c("png"),2)

But for my surprise the after the plot I get :

   "Hit <Return> to see next plot:"
if i do something like :
   plot(cdata,3)

I get:
  Make a plot selection (or 0 to exit):
 
  1:plot  All
  2:plot  Clusplot
  3:plot  Silhouette Plot
  Selection:

As   far   I   know  calling  plot  is using clusPlot() by reading the
"clara" object.
How can I avoid that interaction ?

Thanks in advance

Please proceed in this way:

jpeg(filename = "Rplot%03d..jpg", width = 480, height = 480, pointsize
= 12,
quality = 75, bg = "white")
plot(cdata)
dev.off()

You will get two files (Rplot001.jpg and Rplot002.jpg) in the home directory
where you have your R installed, without any additional interaction.

Regards,
Carlos.

Hi Mark

Does this help?

plot(clara.obj, which.plots = 1)

This was buried a bit in the documentation for cluster.  plot.partition() is
the function used to do the plotting.  See its help page

You need to tell it to do plot 1 or 2 or NULL.  1 gets you a clusplot, 2
gets a silhouette plot, NULL gets both.  In the above command, the
which.plots gets passed though to plot.partition and only produces the one
diagram.

All the best,

Gavin
