[R] PLS regression?

Hi all, I would like to do some QSAR analysis (quantitative structure activity relationship). I need to use some Partial Least Squares (PLS) regression, but I have not seen this option on the R-project. Is it possible to do this kind of regression on R? thank you in advance best regards, olivier

[R] Random number generator in R compared to S

I'm doing some simulations for which i need to use both S-plus and R. I generate in S+ some random normal distributions to define one dataset by iteration. I need to use the same dataset generated in S-plus in R. I was first thinking to generate in R the same dataset by using the same random

[R] Problem with pdf()

Hallo, I noted the PDF format of pdf() beeing PDF-1.1. I would like to know if it is possible to generate PDF files in PDF-1.2. For some strange reason it is not possible to visualize certain pdf files generated via R on IE 5.5 (using AR 5.1). But converting this to PDF-1.2 (using postscript()

[R] export result files (loop problem?)

i'm experimenting with several possibilities produce and export plot/result files. I attempt a lot of things, the file which i want in most ways written but empty, i.e. pdf,write,sink. One exception which works correct for me in the loop is write.table(data,file=dataname). The way without a loop

[R] comparing class() -- R=NULL and S+=numeric

I'm just reading Modern Applied Statistics with S, 4th Ed., Venables and Ribley I'm typing in their examples in both R and S+. I need insight in the difference in the class() statement shown in Chap. 2. Example from book: names(powers.of.pi) - -2:2 powers.of.pi -2-1 0

[R] Is R really an open source S+ ?

This is not a criticism. I'm just curious. Is there an effort to keep R comparable to S+? Or are the two languages diverging? I am doing what probably legions have done before me, and legions will after me...using R on examples from text books written with S+ code. Most of the time everything

[R] Why are default sizes of plotting characters different?

I had occasion to use panel.superpose to draw points in a lattice plot, and chose to set the size to 1.1 using trellis.par.set(). I also wished to add some other plotting characters which I did with grid.points. To get them looking like the same size as those done with panel.superpose, I needed
