Dear r-devel-list, dear John Chambers,
I'm trying to learn OOP-possibilities in R and I was going through the
documentation 'ReferenceClasses {methods}' (great work, by the way...).
Reading associated Examples, something bothers me : it seems to me that there
are errors in 'edit' and 'undo' methods. I think that :
- 'undo' should update 'edits' field with :
length(edits) <<- length(edits) - 1 #(and not - 2)
- and for coherence, 'edit' should store modifications in an 'append'-style :
edits <<- c(edits,list(backup)) #as opposed to c(list(backup),edits)
I hope I'm not wrong and this hasn't been previously reported (I didn't find
anything about it)
Best regards.
PS: I first posted this message on help-list. David Winsemius suggested me
devel-list would probably be more appropriate and was right about that. Sorry
if
you read it again.
PPS: please associate my address when responding because I didn't subscribe to
r-devel-list (I'm still far from being able to follow all its discussions...)
