Hi
Is there any samples anywhere that shows how to build my own R package for Windows?
I read that package manual and well as the FAQ but would prefer to have an example as
well.
I know I need perl and mingw.

Hello All.
I am running R 2.0.0 with a Win XP operating system. The same problem occured
with R 1.9.1 but not with R.1.3.1 on a Win NT computer.
My request is about the following problem with the sort function:

x - 1.0001
all.equal(x, 1)

x == 1

I'd suggest you start by using lda() or qda() from MASS,
benefits being that

in the target population, you can set 'prior' to mirror the target
frequencies. The issue is, perhaps, is your odd person odd in
