R devel - May 2004 - bad interaction between RandomFields 1.1.11 and Sweave

Not really a bug (I eventually discovered), but ...
  When running GaussRF()/DoSimulateRF() with n>1, the default
pch="!"
prints backspaces to the terminal, which causes problems (LaTeX barfs) if 
you're running this within an Sweave() job.  Setting
RFparameters(pch="")
fixes the problem.  
   Could put this in the documentation, but I don't know where you could 
put it that it would attract attention -- wouldn't have occurred to me to 
look at RFparameters before poking through the code to see where the ^H 
was coming from.
  
  I was going to suggest testing interactive() to see if the code was 
running in batch mode or not, but I just tried that with Sweave() and it 
thinks that interactive() is TRUE when running Sweave.  Oh well.  
Any one else have a solution?

Dear Ben,

I do not know how to solve the general problem that backspaces
cause within Sweave, but which are needed to implement running
counters.

To avoid the specific problems for RandomFields, a new version
of RandomFields is uploaded with default "pch="*" instead of
pch="!".

Cheers,
Martin
