[R] A question about par.plot in gamlss

[Prof Brian Ripley]

As the posting guide says, please ask the package maintainer -- I believe 
he does not read R-help regularly.

Your layout is hard to read (please do use spaces and indentation in 
posted code), but probably there is a scoping problem with par.plot used 
inside a function.
