R devel - Sep 2010 - Stats not loaded? Method for as.ts() results in error

Dear list,

 

I've got the following problem:

 

In a package I'm trying to build, there exists a method for the function
"as.ts()". When checking the package, R always throws the error that
it
cannot find a function called "as.ts". To me it seems that the package
"stats" (home of "as.ts()") is not loaded during the
checking process even
though it's a base package. For testing, I've written a method for
"plot()"
to see if it's a general problem with base-functions, but this one passes
just fine.

 

Did anyone of encounter a similar problem or could help me out with a hint?

 

Thank you very much,

Janko

Are you using a NAMESPACE, and declaring your method as a method?  If 
you don't, R will have to guess what the methods are, and it might be 
getting mixed up because of the unusual name of the generic.

Janko,

You don't mention if you are using S3 or S4.  A small example would
make it easier to identify where your problem is.
