[Rd] 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 __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel

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.

Re: [Rd] Stats not loaded? Method for as.ts() results in error
Hi Jeff,
sorry for that! I found the problem in the meanwhile. But since I'm always
grateful to get answers from the list, here's what happened:
I have a method for as.ts()
setMethod(f = as.ts, signature = Tsi, definition = function(x, ...)
{
Function body
})
This is the error I always got while running R CMD check
Error in setMethod(f = as.ts, signature = Tsi, definition = function(x,
:
no existing definition for function as.ts
What I was too stupid to see is the fact that as.ts() isn't a generic in the
first place. Yet, I turned it into one somewhere in my code (which I forgot
;-)) and when I tried to debug my code manually I always misleadingly took
it as an innate generic and wondered why R CMD check always complained about
that fact that it couldn't find it.
Regards,
Janko
