That explains it. Thanks. I don't need rownames though, as I'll only ever
use integer subscripts. Is there anyway to drop them, or even better not
create them in the first place? The memory saved (90%) by not having them
and 10 times speed up would be very useful. I think I need a data.frame

Have you tried just copying your data from your email (this mail, e.g.)

characters, ensuring a newline at the end of the last line, and then
using read.table (perhaps via the clipboard if you're on Windows)?

Beyond asking why, and not letting R do work for you, let me just note
that inverting the full matrix is often computationally wasteful. You
can take the Cholesky decomposition M = L'L where M is your matrix and
then only work with L. Other than that, there are two packages for
dealing with sparse

Hi Ariel,
ok, you want to change the language?
Right click on the R icon on the desktop, choose "Properties". In the
field "Destination" you add at the end of the line":
language=it" (Italian) or " language=fr" (French)
Then the line should look somewhat like: (for Italian)
C:\Programs\r
If your data frame is X then
unstack(X, value ~ type)
gives you a list with x and y components. If you need
these as variables try attach(unstack(X, value ~ type))
or
with(unstack(X, value ~ type, {
... some computations ...
}

You can change the language setting during the

the "selection components" step of installation,
uncheck the "message translations".It should be OK
then.

That's Rdbi, not DBI, and so not the question. (Rdbi is a precursor to
DBI, and DBI is now ca 5 years old.)
I've heard nothing about a PostgreSQL driver for DBI for a long time.
Meanwhile, RODBC continues to work with PostgreSQL, as it has done for
several years.
