DeaR list,
Pardon the stupidity of this question but I've been trying this for
a while now without success.
I've followed the example given in the green book "programming with
data", and I now have a working example of a S4 class with a few
methods (plot, summary, as.data.frame). It's all very nice in one
file, but I cannot find the way to put this information in a
package. I've created several simple packages (without S4 classes)
in the past using package.skeleton and manual editing / adding of
some files.
The question I have now is where do the setClass and setMethod live
in the folder tree? I sort of believe they should be defined in a
source file in the sub-directory R/, but is there a special name to
give to these files, how do they get recognised during installation
or build?
I've tried to find the answer in "writing R extensions" but I must
have missed the relevant section.
I don't think there's any particular name needed for the file. I had
a look at Matrix for an example when I was writing an S4 package, and
kind of followed what they were doing. In my example, I had one file
that had all the setGeneric calls, and another one named after my S4
class containing setClass and setMethod. And then you need to work on
the NAMESPACE file. I think to some extent this is described in
"1.6.6 Name spaces with formal classes and methods".
Hopefully someone more experienced than me can offer a more
authoritative answer.
Many thanks,
Sincerely,
Baptiste
