[Rd] naiveBayes.plot does not accept ask=FALSE (needed for use with tkrplot)

[Dominik]

Dear mailing list members,

I am writing a tiny tcltk interface for a few basic classification 
methods which should also include plotting density curves with 
naiveBayes.plot() and tkrplot(). I try to replot the curve using the 
next input variable of the NaiveBayes by clicking a button in the 
tkrplot window. Well, it kind of works but:
Now I want to make R stop asking me to "Hit <Return> to see next plot"
The plot function does not accept the parameter "ask=FALSE". Warning: 
parameter "ask" could not be set in high-level plot() function.
If I precede par(ask=FALSE), nothing changes. Well, I am really not 
shure wether I use "par()" correctly. (please see function plotfun() 
below) What do I have to do to run R completley in batch-mode?

thank you in advance
any hint would be greatly appreciated
