Version information for S4 classes --- elementary version management
...s not a "large" object.
Based on this package version information, (elementary)
version management could then be provided by means of
generic functions
getClassVersion() [as described in the Green Book, 7.4]
conv2NewVersion() ## by default issuing an error ("Not yet defined")
isOldVersion() ## true or false; by default NA
Defining particular methods for his classes, a package maintainer
could then issue specific warnings or --- at its best --- even
provide coercing methods.
What do you think about this?
