Now I am also trying to do the wrapping into the 'modern' S4 classes. This is the 5th day I am working on this and I have to say S4 was not design for big packages!
(1) Because of its meta-data design, the setClass commands must be sorted in the order of inheritance and this is a real pain when it comes to a few hundered classes. I wrote some R code to read the annotated source files and return the ordered file names.
(2) After all, when I put the ordered file list in front of Collade in the DESCRIPTION file, I got this error induring installation:
---------- Making package vtkr ------------ adding build stamp to DESCRIPTION Error in .read_description(dfile) : file 'DESCRIPTION' is not in valid DCF format Execution halted make[2]: *** [frontmatter] Error 1 make[1]: *** [all] Error 2 make: *** [pkg-vtkr] Error 2 *** Installation of vtkr failed ***
After a bit playing with th enumber of th efiles, it seems to me Collade cannot handle (probably) more than 256 files.
For many good reasosns, I am not going to break the package up into different pieces. If I am not missing anything here, I hope some R developer can let me know about some work around on this bug. (hey even java and python don't have this limitation, not sure about Ada83.)
