am I right in the assumption, that for calculation of the condition numbers I have to use the correlation matrix of X, and not t(x) %*% x? > e <- eigen(t(x) %*% x) better (x must not have a first column of ones): > e <- eigen(cor(x)) > e$val [1] 6.6653e+07 2.0907e+05 1.0536e+05 1.8040e+04 2.4557e+01 2.0151e+00 > sqrt(e$val[1]/e$val) [1] 1.000 17.855 25.153 60.785 1647.478

I installed the latest R-package "R-2.1.1-1.rh4AS.i686.rpm" on a Red Hat Desktop 4 (RH EL4) machine. When I try to get help by the help.start() command an error message appears: ----- > help.start() Making links in per-session dir ... If '/usr/bin/mozilla' is already running, it is *not* restarted, and you must switch to its window. Otherwise, be patient ... sh:

Hello experienced R-ers, I'm converting from S-Plus Win 98SE to SuSE 8.1, R 1.62 and have run into som problems. 1) When I use help.start() netscape comes up OK and all links are accessible except "Search Engine & Keywords" : search doesn't work and the keywords from base doesn't respond either. ?command within R gets netscape running and works OK. 2) I haven't

Hi I need to overlay two pixmaps (library (pixmap)). One, a pixmapGrey, is the basis, and on this I need to overlay a pixmapIndexed, BUT: the pixmapIndexed has set only some of its "pixels" to an indexed color, many of its pixels should not cover the basis pixmapGrey pixel, means, for this "in pixmapIndexed not defined pixels" it should be transparent. What would you

I am just about working through Faraways excellent tutorial "practical regression and ANOVA using R" on page 24 he makes the x matrix: x <- cbind(1,gala[,-c(1,2)]) how can I understand this gala[,-c(1,2)])... I couldn't find an explanation of such "c-like" abbreviations anywhere. thanks for a hint. another problem: I couldn't load the faraway library, using the

Christoph -- There was just a thread on this earlier this week. You can search in the archives for the title: "refitting lm() with same x, different y". (Actually, it doesn't turn up in the R site search yet, at least for me. But if you just go to the archive of recent messages, available through CRAN, you can search on refitting and find it. The original post was from William

I hope this question is adequate for this list I use the nnet code from V&R p. 348: The very nice and general function CVnn2() to choose the number of hidden units and the amount of weight decay by an inner cross-validation- with a slight modification to use it for classification (see below). My data has 2 classes with unequal size: 45 observations for classI and 116 obs. for classII With

Following the beginning tutorial, I typed help.start() and was given a choice of browsers. I picked chrome but got back that chrome is not found. I cannot seem to change or get rid of it now. I looked at /etc/R/Renviron but don't see anywhere to set browser (R_BROWSER = ${R_BROWSER ...etc) - nothing about chrome. I tried starting as "R_BROWSER= R" - same thing. How do I change the

I usually startup R from within several directories (usually where the programs or data of interest are). I like to use a small web browser called dillo to browse help files. However, by default R looks for mozilla, so I have to type every single R session: > options(browser='dillo') Is there anyway I can change this globally? thanks, J.

again, under another subject: sorry, maybe an all too trivial question. But we have power data from J frequency spectra and to have the same range for the data of all our subjects, we just transformed them into % values, pseudo-code: power[i,j]=power[i,j]/sum(power[i,1:J]) of course, now we have a perfect linear relationship in our x design-matrix, since all power-values for each subject sum up

System info: Mandrake 9.0 R Version 1.6.1 ESS 5.1.21 Emacs 21.2.1 ------------------- Colleagues I understand that help.start() search function works with netscape and although it may also work with latest versions of mazilla it doesn't seem to with the one I'm using (Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.1) Gecko/20020826). I thought that there were instructions for setting

> Package: r-base-core > Version: 1.5.1-0woody1 > Severity: minor > > I don't have Netscape on my system. Trying to follow the sample To best of my knowledge, this R feature dates from a time when Netscape was essentially the only browser out there. It also had a most useful feature: you could attach new request (resulting in a new "frame" in X11 / window manager

Hi, dear R pros I try to understand eigen(). I have seen, that eigen() gives the eigenvectors normalized to unit length. What shall I do to get the eigenvectors not normalized to unit length? E.g. take the example: A [,1] [,2] V1 0.7714286 -0.2571429 V2 -0.4224490 0.1408163 Calculating eigen(A) "by hand" gives the eigenvectors (example from Backhaus,

Hi, The function help.start() assume that the brower is netscape which is no longer the dominant brower in used. I am using now opera and other use mozilla or Microsoft IE. I can always type help.start(browser="opera"), but it is not convenience: I would like to be able to set the default brwsernone for all. But the real bug is that even after launching

Dear all, I have a question regarding the .First function. I have included help.start() and several libraries in my .First as: .First <- function() { help.start(browser = "netscape7") library(lattice) library(modreg) library(splines) library(MASS) library(maps)} The libraries maps and splines do not seem to be available when I start R, but I have found if I change the order

I've been kicking the following idea around for a while, and am now proposing to put some version into 1.7.0. I'd be interested in comments on the desirability and the design, before I start writing any code. S4 introduced a file .S.chapters which can contain a list of S chapters (equivalent to R packages) to be loaded on start-up. This was the germ of this proposal. Proposal: Extend

Hello, I am trying to build the R-2.11.1 software for university faculty to use in research projects on a DEC/Compaq/HP AlphaServer model GS160 16CPU/64GB memory running Tru64Unix aka OSF1 version 5.1B-5. Is it known whether it is possible to build the R-2.11.1 software on the platform I am using? In my attempts to build the R-2.11.1 software, I first used the native C and Fortran 77/90/95

Dear list subscriber, I am quite puzzled by the behaviour of processing Sweave files within an R session, i.e. Sweave("foo.Rnw") versus R CMD Sweave foo.Rnw In the former the environmental variable 'SWEAVE_STYLEPATH_DEFAULT = TRUE' is obeyed (this is set in etc/Renviron.site as well as under the users home directory in .Renviron). That is the hard-coded path to Sweave.sty is
