R help - Feb 2003 - ClustPlot question

Hi...  Being new to this mailing list I have small question to make.
  I am using R in Windows.
  I  have  several  clust plots to make but each time I call "plot" it
  stops  asking  for  a  "graph  type". How can I disable that kind of
  interaction  ?
  For   each   plot  I  am using the "savePlot" function, is there any
  other way of exporting the above plots ? in a Non-interactive manner ?

  Greetings in advance
