Michael Z – this might be something
that Mike Sumner can discuss with you, since he’s a big fan of R and (I
think) deals with similar direction-change / tracking data, though his
GIS-of-choice is Manifold. I’m not sure his data quantity is as large as
yours, but maybe it is. (Michael S – hope this is in order) Ian Thomas From:

[mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] G’day, Apologies for being slightly off-topic. I’d like a
recommendations of a free, basic, statistical analysis software package. I’ve Googled “free stats software” and found
quite a few sites that list multiple candidate packages (and I’m looking
at a few of them) but I thought it would be useful to get the opinion of people
that might be using something good, and using it with MapInfo. This is
for situations when the number of records exceeds the capabilities of Excel. As an example of the type of very basic descriptive stats I want to
do, I have a table that results from a positional change-detection query in
MapInfo that has resulted in a table with about 150 thousand records that shows
how much an address point has moved between two releases of an address
database. The distances vary between sub-millimetre to several hundred
kilometres. One of the first things I want to do is create a range of bin
sizes. For a select few of these I may want to produce a histogram
or two, or a box plot. I’m not looking for an integrated solution. This would only
be used for ad hoc data exploration, not as part of an application, If you’ve use a bit of stats software that sound like what
I’m talking about, then I’d like to here about it. Meanwhile, I’ll get back to reading the “R”
manuals. Regards Michael Michael Zatorsky Interfaces, Integration & Info Analysis Team QPRIME Project, Operational Policing Program p. +61 7 3015 5566
