Daer all, I have the problem. I could not run the regression, because I have always the warning message "memory.size". from the help file I learned that it is possible to increase the memory size, but I did not undestand how could I do it. Could you please explaine it to me. I would be very grateful for it. The second question: I obtained from the regression the coefficient "6.003e-3" and "0.0345e+3". What daos it mean? Thanks a lot, Silika

Additionally, tell us the Operating System and your version of R as well (assuming the recent R-1.7.1).

What daos it mean?scientific notation: 6.003e-3 = 6.003 * 10^(-3) = 0.006003 0.0345e+3 = 0.0345 * 10^(3) = 34.5 Uwe Ligges> > > Thanks a lot, > Silika > > ______________________________________________ > R-help at stat.math.ethz.ch mailing list > https://www.stat.math.ethz.ch/mailman/listinfo/r-help
How *exactly* did you "run the regression" in R? There are several ways, and it can make a big difference for large data sets. lm() would be the most expensive option. If I'm not mistaken, lsfit() is more "lean and mean". You can even do it more or less by hand, by calling qr() directly. There's also a disussion in Venables & Ripley's "S Programming" on this subject (for Splus).
