Hi,

I thought I would just jump in on this as I am running an i7 as well.
I use
hmisc for the doBy functions and it would make a huge difference
particularly with large data sets to run this on 64bit windows. I'm not
sure how to compile from source and usually use the install.packages
option. At the moment I have two versions of R installed and switch
between
them depending on what I'm working with. Having an hmisc package for
64bit
windows would really help.

Thanks Natalie
Natalie you must be thinking of another package. doBy is not in Hmisc.
summarize, mApply, etc., are in Hmisc.

You might look at the data.table package too.
Additionally, If you install the 64-bit version of R-2.11.0, you can 
simply install.packages("Hmisc") and you got it - giben you are really 
talking about "Hmisc".

Zach,

The R-gurus will correct me when I'm wrong, but as far as my very
limited

experience goes, the 64bit version only gives you an advantage when
throwing

around huge datasets or doing very memory-intensive tasks. For most
of the

things I do with R, there is no difference at all. Now the difference

between an old x86 and a new quadcore i7, that's another story...

thanks Joris,

the reason I am looking for the instructions is that I hope 64 bit
hmisc

will run better(faster) than 32 bit on 64 environment.

Regards,

Zach.

Puzzling question. You install R, you click on "install packages", you

select a mirror, you select hmisc, and done. There is a 64bit version
of R,

but a 32bit runs smooth on a Windows 7 64bit as well. if you love the

command line, look at ?install.packages.

I can't see why you would like to compile an R package yourself. So in
case

you have a specific problem, a bit more information would come handy.

Cheers
