suspect that I could iterate across the results of name(x) and somehow
use quote() and eval() to solve this problem, but I cannot seem to
make it work. Any suggestions would be greatly appreciated.

linear correlation?
Whether the two variables have the same units does not matter. Moreover,
even if there were some way of converting cm to kg the correlation would
still be the same because the correlation is invariant under unit conversion
as it is invariant under multiplication of its arguments by a constant.
As for your second question, the correlation estimator is a continuous
function of each of the

warnings associated with logistic regression
.... A read of Hosmer and Lemeshow (1989) does not
provide much insight, so I thought that I would post the question to
the list.
Any comments? Also, I'd be happy to email a dataset that exhibits this
behavior if anyone is curious enough.
Cheers,
A.

recategorizing a vector into discrete states
Hi All,
I'm trying to take a numerical vector and produce a new vector of the
same length where each element in the first is placed into a category
given by a 'breaks-like' vector. The values in the result should equal
the lower bounds of each category as defined in the breaks vector.
I suspect that a vectorized solution is pretty simple, but I can't
seem to figure it

enumerating non-overlapping pairs of elements from a vector
Hi All,
I'm trying to come up with a clear and concise (and fast?) solution to
the following problem.
I would like to take a vector 'v' and enumerate all of the ways in
which it can be broken into n sets of length 2 (if the length of the
vector is odd, and an additional set of length 1). An element of 'v'
can
only appear in one set. Order within sets is not important.

problems linking c++ code
I've been trying to learn about dynamically loading subroutines in R.
Ultimately I would like to use this approach to implement some
simulations. For the moment though, I've run into a problem compiling
c++ code and loading it into R.
The 'C/C++' and 'R'code below works fine when compiled and linked with
gcc, but gives an error when the library is compiled and linked with
