Andy,

Thanks. Note that DeVeaux's book, at
www.williams.edu/Mathematics/rdeveaux/book/book.html, is marked "For use
only by students of Math 244 Spring 2001, Williams College" and
"DRAFT: do
not distribute or copy".

Hi!

I have two questions:

1.  Is there an easy way/algorithm to obtain a series of permutated data
matrices which are obtained by permuting all the elements within each row?

Or is there a function that can permute all the elements for each row
instead of the whole matrix?

2.  Is there a function which helps find a matrix... projection operator
from p dimensional to p-1 dimensional subspace orthogonal to x, a real
number?


Thanks for your help!
