Very Large Data Sets

List, Can R handle very large data sets (say, 100 million records) for
data mining applications? My understanding is that Splus can not, but
SAS can easily. Thanks,Tony Fagan

From a theoretical point of view yes, but practically:

1) you'll need plenty of memory
2) even than the computation time will be long

In past times I used SPSS to create summarized data file (Mostly there is much more data than really needed). Now I cut the data in a view records, write the syntax, and than run the code in the night.

I think the ++ of R is the flexibility of the analyses not the data preparation of very,very large data-bases.

Merry Xmas & a happy new year
