Dear Tom -- Thanks for your attention to my problem.
I believe the problem with using Calc as a viewer is that I have 3.6
million lines of data.
But I am getting more comfortable with using R itself to answer these
questions. I think part of my problem is that it is the nature of of legal
training to try to andticipate every possible problem. But when the number
of possible problems exceeds a certain level, my brain runs out of working
memory even if my computer still has RAM.  Also, I set ambitious goals for
allowing people to run my software on ordinary laptops a year or three old.
I have to say that since I have scaled those back and got 24 gig of RAM
instead, many problems seem more manageable, even without a database.

Peace, Andrew

Hi :)
Ahh, Base seems to be better when the data is held externally.  Postgresql
should be an excellent choice for holding the data and then 'just' get
Base
to connect to it.

I would have thought Calc would then be really good at displaying the
data?!  So i'm not sure what the problem is now.  Hopefully someone better
with databases might be more helpful!  Errr, most people on this mailing
list seem to be better with databases than me!
Good luck and regards from
Tom :)

Thanks Tom!

Gnumeric is a great product and I have used it before. I was hoping to
use
Calc in this case because I am trying to learn to use the LO database,
Base, as a stand-alone or a front end for PostgreSQL. But I find it very
hard to define, use, and even just to import a file into a database if I
can not first look at it and determine how missing variables are coded,
which fields are character and which are numeric, etc. Some census
products
are really good at giving users this kind of metadata, others not so
much.
(The Economic Census metadata is hard enough to read and understand
(would
you put material intended to explain something to the public in
pipe-delimited text?) that I have written to them asking for meta-meta
data). So I wanted to use Calc for exploration and base to do the heavy
lifting, in the hope that things might be easier if I stayed withing one
document family. Now I am thinking that some other approach will be
easier.

Warmest regards, Andrew

Hi :)
Try Gnumeric;
http://www.gnumeric.org/download.html

It's a dedicated spreadsheet program with a tiny footprint that uses
minimal resources, so it's faster, lighter and more robust than Excel
or Calc.  Many people find Gnumeric to be better than Calc or Excel
for serious or hefty spreadsheets and/or for handling many more
spreadsheets in a shorter time-frame.

It can be installed alongside LibreOffice and/or MS Office.  It uses
the same format as LibreOffice natively so most spreadsheets can be
bounced between the 2 programs quite happily.

Part of the advantage of LibreOffice is that it fits well into a wider
eco-system and co-operates well with a wider range of programs and
suites allowing you to tailor individual machines to specific
use-cases and yet still retain the ability to share files between
different machines and different people using different OSes and
programs.

Regards from

I am working with a data set that keeps causing my LibreOffice to
freeze.
I
am pretty sure that this is only because it is big. It is a
pipe-separated
text from the US Economic Census imported into Calc, about 30
columns
and
around a million rows. (The actual data set is bigger, but Calc
quits
at a
million-odd. The complete file is about 0.8 gig.) I suspect but can
not
prove that this is related to file handling somehow, e.g. breaking
down
during auto-saving. The first time I saved the data as a Calc file
it
took
nearly an hour with the "soffice.bin *32" process running at 25
percent
of
CPU time and using about 825 meg of memory the entire time. (Not
sure
why
this is showing up as a 32-bit version).  And when Calc freezes,
all
the
LibreOffice programs freeze. So I can't just switch to another file
and
noodle away while waiting.


It looks to me as though Calc cannot handle more than 1048576 rows
of
data,

Do you have more rows than that? If yes, then I think that you
cannot
open
the file.

If you have less than that, and, if you think that you are simply
running
out of memory.... if you can figure out how to get the data to me, I
can
run
a test on a 64 bit version (running on Linux). My machine has 32 GB
of
RAM...
