[R] Posting an 'S4-creating Package Problem'...

[Daniel Kosztyla]

Hello R-Team,

May you help me to post a 'S4-creating Package Problem'?
Thanks already now for supporting.
The problem sounds like:

Hello R forum,

while compiling my R-package these 'Warnings' occur:

...
Warnung in matchSignature(signature, fdef, where) :
   in the method signature for function "plot" no definition for class: 
"prediction"
Warnung in matchSignature(signature, fdef, where) :
   in the method signature for function "plot" no definition for class: 
"validation"
** help
*** installing help indices
...

Maybe my NAMESPACE file looks wrong. Has anybody an idea how it has to 
look like to solve
this problem? ( I use exportClasses(...), exportMethods(...). )

I have 3 classes: 'prediction', 'validation', 'nvalidation' which have a 
plot function.
There's no warning for class 'nvalidation' but for the other two.
Any suggestions?

Greetings. Dan
