Yes, he is exactly right. The homework code that I gave you throughout is acting extremely strangely on 1.7.1 and also on 1.7 Perhaps this explains some of the problems that some of you are having. I have no explanation for why these problems occur. Will someone please let me know whether the data center is loaded with 1.7 and 1.7.1.

Hi~ everyone! For those who get following "warning" message: Warning message: longer object length is not a multiple of shorter object length in: approval - predict.lm(lmfinal, data.approval) Try the 1.8.1 R version (I think some of us, including me till this morning, use 1.7.1 instead of 1.8.1). You may get the right result! (I found this a few hours ago...)
