R help - Nov 2010 - Is it possible to make a matrix to start at row 0?

I want to make the matrix to be indexed from row (column) 0, not 1
Can I do that? How?
Thanks

Hi,

You can do it, but it would be very difficult (think reworking all
indexing yourself) and you probably should not even try (nothing else
that was expecting indexing to work as the R gods intended it to would
work once you had done your rework).

What has lead you to want to index from 0?  If it is some problem you
are having, I can almost certainly promise you it will be easier for
us to show you how to approach it differently and index from 1 than to
change the underlying framework so you can index from 0.

Cheers,

Josh

Eh??? Why would you want to do that?? (R isn't C).

So the simple answer is: you can't.

The other answer is, well of course you sort of can via, e.g.

for(i in 0:9)  {
   z <- myMatrix[i+1,]
  ...
}

But as Josh said, I think this falls into the class of "You are just
asking for trouble, so don't do it."

Cheers,
Bert

Try the Oarray package...  it did have some problems at one time, but maybe
it has been updated since then.
