How to calculate the number of classes has changed.
The expected result is
- class changed 2
- class unchanged 3
The actual structure of your "data set" is unclear. You appear to have
your data stored in a number of separate data frames, but this is not
made explicit. The details must be specified in order for anyone to be
able to help you.
Moreover it is not at all clear what you want to achieve.
Why is "class changed" equal to 2 and "class unchanged" equal to 3?
I count 2 "no"-s and 11 "yes"-s (not 3 "yes"-s).
There are many clever people who subscribe to the R-help list, but few
if any of them are mind-readers.
