too many entries for Rs architecture to know how to store in
memory, even if I had memory that was big enough to store it.
Again, Im no expert in this so I may be wrong.

guessing the problem I was having would occur when ever this
happens and people have the old package in their personal libraries.
(which would likely be the case if it's considered good enough to add to
base R)
Not really a 'bug' of R. But something I'll remember!!!
Thanks again.
Chris Howden
Thanks for the explanation Brian,
I used the summary(packageStatus()) to have a look at what was available
and in each library. And then deleted all libraries that came with R2.12.0
from my personal library.
And everything now works.

The first argument in download.packages should be of type character or

Does anyone have any ideas?
At the moment my best idea is to hand it over to someone with a dedicated

can do the modelling)
Thanks for any ideas at all!!

a cbind and not a merge U might be able
to use one of the following packages. These store the data on disk (rather
than RAM) and might allow u to cbind them.

I'm not that familiar with this type of data.
I just had a similar issue, but had a GIS person do it in Arc view.
But maybe try some of the following functions?
Match

Plus I'll forward U the replies I got to my post
Good luck :-)

From:
data.frame or matrix?
Are there other special functions out there that can handle this type of
data, and I should be using these instead?
Thanks for your help
