RE: [R] vector

If you have all your vectors in a list vl - list( p1, p2, p3) the the following should do the trick: res - numeric(0) for( i in 1:length(vl) ) res - c( res, vl[[i]] ) Bendix Carstensen -- Bendix Carstensen Senior Statistician Steno Diabetes Center Niels Steensens Vej 2

Dear Colleagues, I would like to do classification using logistic regression. Which R package can I use? Also is there any package for feature selection for logistic regression based method? Thanks a lot in advance. Happy holidays. Regards, Raj [[alternative HTML version deleted]]

Re: [R] how to ignore t.test error message

Hi Although t.test does not give an error with t.test(c(0, 0), c(0, 0)); if you try doing that with any number other than 0, t.test(c(1,1),c(1,1)) (R gives the following error) Error in t.test.default(c(1, 1), c(1, 1)) : data are essentially constant The logic in insisting is

[R] RandomFields: Controling seed with GaussRF

Hi, I'm using RF to simulate a correlated variable with GaussRF set.seed=1 GaussRF(sim.kfinegrid, grid=F, model=exponential, param=c(0,0.5,0,0.2)) However when I simulate again using the same random seed I get different results. set.seed=1 summary(GaussRF(sim.kfinegrid, grid=F,

Is there a way to save plots and use in a word document. Thanks for your help in advance. durai __ Send holiday email and support a worthy cause. Do good. __ R-help@stat.math.ethz.ch mailing list

RE: [R] plots

Yes. Assuming you are using R in Windows, right click on the plot, and choose Save as metafile, or more expeditiously, Copy as metafile, and then paste directly into your WORD document. Charles Annis, P.E. [EMAIL PROTECTED] phone: 561-352-9699 eFax: 614-455-3265
