[R] Stats help for dissertation project

[Michael Dewey]

Dear Raija

This list is primarily for R programming questions so most of your post 
is off-topic here. If you are registered for a degree presumably someone 
is paying a fee to your institution and someone there is being paid to 
supervise your project so I would have thought they would be the first 
port of call. If they fail to meet their obligations then there is a 
site Cross Validated where you may have better luck.
