Hello Everyone,
 
I've been asked to check if there is a significant difference in the following:
 
                  Pre        Post
Group A     15/19     14/19
Group B     14/19     10/19
 
My sense is that I need to perform McNemar's test on these data because responses are correlated within patient from the pre-test to the post-test.
 
The question is how to do this. I'm a SAS user who is learning R. I'm not sure how to do this in SAS and am even less certain about how to do it in R. The R books I have don't seem to cover this. At this point, I'm not even sure if the information I've been given is what I needed to perform the test.
 
If anyone can help with this, it would be greatly appreciated.
 
Thanks,
 
Paul
