I believe that Splus 6.2 has a native interface to SQL server so that S-PLUS
ODBC is no longer required.

Subject: Re: [S] Large data sets
"Large" data set is all relative. Some people might think 1Mb is large, but
that's actually tiny by the standards of current machines. I regularly use
data objects in the region of 100Mb in S-plus under Windows 2000 on a
machine with a couple of Gb of RAM. I have no idea if that is "gigantic"
or small for you. (I'd think that a current reasonable interpretation of
"gigantic" would be terabytes.) On a Unix machine with more physical memory
(and 64-bit addressing) you could work with proportionally larger data sets.
I think Insightful might be planning some more features in S-plus to perform
analysis on data sets larger than will fit in S-plus -- you might want to
check with them regarding features and timelines.
If you're planning to use ODBC you might want to verify that it will not be
a bottleneck for your analysis.
hope this helps,
Tony Plate
