Some clarificatins of anova() and summary ()
I think now I have got some understanding of the things. y ~ x1+x2 first adds x1 to the model and then adds x2 . But y~x2+x1 adds x2 first, so the value we get are different. please correct me if i am wrong.

anyone please explain why this happens.. I know this happens when x1 and x2 has different sizes. but here x1 and x2 have same dimension.
Given that this is a homework problem, I think the onus is on you to figure this out, not on us to help you. In almost all classes, you are expected to work on homework by yourself, and not solicit help from others - this is often known as "cheating". Hadley -- http://had.co.nz/
