R 2.6.0 S4 data breakage, R _data_class(), class<-, etc.
...could fix all of them with just 'a <- asS4(a)' and save()
(they are relatively simple objects just missing the S4 object
bit flag)
b) I am surprised one of them were actually saved from 2.5 - our buggy
code no doubt, see below.
We never noticed we didn't do SET_S4_OBJECT() in our C code nor
asS4() in our R code until this week. Obviously we were mistakenly
relying on the S4 method dispatch on S3 objects, which were withdrawn in
2.6.0...
2) I am surprised that 'class(a)' can read S4 class names, but
'class(a)<-' does not set the S4 object bit....
