Gene, You might want to look at function read.csv.ffdf from package ff which can read large csv-files into a ffdf object. That's kind of data.frame which is stored on disk resp. in the file-system...

Dear John, I checked for the uniquenesses from factanal() and found out that these estimates need an a priori assumption about the number of latent factors (and they depend strongly on that assumption). What I want is an estimate of...

Dear All, Are there recommended functions to test for (exact) significance when the samples are drawn from small finite populations (which sometimes are not much bigger than the sample)? I am looking for - differences in central tendency - differences of proportions...

Dear all, Will R run under Win2000 or is it safer to stay with NT4.0 for a while? Regards -- Dr. Jens Oehlschl?gel Analyse BBDO InterOne Gr?nstr. 15 40212 D?sseldorf Tel.: +49 (0)211 1379-187 Fax...

- sorry the previous mail went out by accidentaly hitting a key, here is the end - .. please rethink, if there is any way to get that fixed. I mean, do we really have to expect S+ code to break, because it...

Dear all, to avoid reinventing the wheel: has anyone included compression algorithms into his library? Best NEW EMAIL jens.oehlschlaegel at bbdo-interone.de -- Dr. Jens Oehlschl?gel Analyse BBDO InterOne Gr?nstr. 15 40212 D?sseldorf Tel.: +49 (0...

Daniel, Thanks for answering. > your AIC is monotonic increasing That was the reason I suspected something is wrong, but what? Either the way I calculate the number of estimiated parameters? Or the (scale of the) Likelihood itself? > Have you tried...

And here is a second solution, that differs in what happens if the variables have differing lengths: > var1 <- 1:4 > var2 <- 1:3 > sapply(ls(patt="^var[0-9]"), get) $var1 [1] 1 2 3 4 $var2 [1] 1 2...

Does anyone know about functions for calculating Somer's D in R? Perhaps even a version for censored values, like the two functions in hmisc? Thanks for any pointers -- Dr. Jens Oehlschl?gel-Akiyoshi MD FACTORY GmbH Bayerstrasse 21 80335...

Dear R-experts, I just tracked down a nasty bug in a dynamically parametrized function to wrong argument matching. As we get more and more complex applications build on top of R (like bioconductor) partial matching gets more and more...

Dear all, I try to submit a library to CRAN but can't overcome the last R CMD CHECK. Can someone enlighten me how to put the \usage{} section for an S3-Method extractor defined as > args(get("[.refdata")) function...

Hello, I'd like to ask whether there is a prefered linux distribution for use with R (Suse, Redhat, Debian) and what fortran compiler is recommended (f77 or f2c)? Thank you -- Dr. Jens Oehlschl?gel Analyse BBDO InterOne Gr?nstr...
