Hi I tried to customize help(), so it starts the compiled html help, and searches in all packages. I wrote the following function: > my.help function(topic){ help(topic, package=.packages(all=T), lib.loc=.lib.loc, chmhelp=T) } When I use it with >my.help(help) give the following error: Error in help(topic, package = .packages(all = T), lib.loc = .lib.loc, : No documentation

Hello I'm trying to calculate 2d confindence bounds into a scatterplot using the function "kde2d" (package MASS) and a contour plot. I found a similar post providing a solution - unfortunatly I do not realy understand which data I have to use to calculated the named "quantile": Post URL: http://tolstoy.newcastle.edu.au/R/help/03b/5384.html > (...) > >> Is

Dear all I have a big matrix of standardized values (dimensions 285x5829) and R fails to calculate the principal components using prcomp() with the following error message: pc <- prcomp(my.matrix) Error in La.svd(x, nu, nv, method) : error code 1 from Lapack routine dgesdd Is the matrix too big? I'm using R-1.8.1 under Unix (Solaris8) and Linux(Suse 8.2). I tried to perform a principal

Dear all, I am using Cairo version 1.4-5 for plotting R graphs on a Gentoo system that does not have X11 installed. I have full control on the fonts when running R in interactive mode. But when running R in batch mode I cannot change e.g. font size. Letters (including symbols) are, however, drawn. I am exporting the following environemntal variables when running R in batch mode to point to

Dear all, I've sent this question to the r-help mailing list, but maybe it is better suited for the r-sig-debian mailing list, although this is not Debian (but still Linux): I am using Cairo version 1.4-5 for plotting R graphs on a Gentoo system that does not have X11 installed. I have full control on the fonts when running R in interactive mode. But when running R in batch mode I cannot

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

Dear all, I've got many responses to my initial question, which is stated below. However, from those responses it has become clear that I need to rephrase my problem. All responses dealt with subscripting the data matrix before 'apply' is run on it. But this is not want I wanted to do. 'apply' cycles through rows or columns of a matrix, and runs a function on each row or

Dear all, I am stuck with a problem that might be trivial for most of you (and therefore is a bit embarrassing for me...): I want to calculate a generalized least squares regression using two time series (Y depending on X) with an autoregressive correlation structure of order two (the data along time are given below). I use 'gls' from package 'nlme': Calib.gls <- gls(Y~X,

Sorry, I am sure, this must be documented somewhere (but there are that many docs and tutorials to scan for topics..., actually a great thing... but if you are in a hurry..): I want to save a plot as .ps (or .eps): > postscript("plot1.eps", horizontal=FALSE, onefile=FALSE,height=8,width=8,pointsize=10) > plot(hpfit$fit,rstudent(hpfit),xlab="Fitted

Hello everybody, I have a question. I would like to get a correlation between constitutive and induced plant defence which I messured on 30 plant species. So I have table with Species, Induced defence (ID), and constitutive defence (CD). Since Induced and constitutive defence are not independant (so called spurious correlation) I should do a randomisation test. I have a syntax of my

Dear all, I am having exactly the same problem as Andy on an Intel Mac (see below / https://stat.ethz.ch/pipermail/r-sig-mac/2009-May/006208.html) with the degree symbol. I am using R version 2.11.1 (2010-05-31) on Xubuntu 10.04 with Windows fonts copied from /WINDOWS/Fonts and included via 'sudo dpkg-reconfigure fontconfig' and 'sudo fc-cache'. Any help would be highly

Dear R-users, dear Prof. Ripley as package maintainer I tried to investigate the odd error, when I call nnet together with a 'weights' parameter, using the 'fgl' example in V&R p 348 The error I get is: Error in eval(expr, envir, enclos) : Object "w" not found I think it is a kind of scoping problem, but I really cannot see, what the problem exactly is. and

Dear R-users I would like to draw a barplot with a special y-axis. Most of my data points are in the range from -50 to 50, apart from one value that is 550. I would now like to have a y-axis from -50 to 50, then a "break" and the "rest" of the y-axis, let's say from 500 to 600. In order to make clear what I'm trying to do, I attached a figure. Is it possible to do

Dear R-users I use nnet for a classification (2 classes) problem. I use the code CVnn1, CVnn2 as described in V&R. The thing I changed to the code is: I define the (class) weight for each observation in each cv 'bag' and give the vector of weights as parameter of nnet(..weights = weight.vector...) Unfortunately I get an error during some (but not all!) inner-fold cv runs:

I started the graphics device with X11(). When I tried to plot a tree object with > plot (tree) It gives me the error message: Error in plot.window(xlim, ylim, log, asp, ...) : invalid xlim I was looking in the manual under "plot", "plot.window", etc. but I didn't really get the resolution of my problem..... What's the problem? I'm runnig R on a SuSE 6.0

Hi, I’m Nicole Haenni and I'm doing research for my thesis at the University of Berne (scg.unibe.ch) with Mircea Lungu and Niko Schwarz.

It takes about 10 minutes to complete it. A software

Hello there I ` m a newbie in R and have a question about the output of write.table My command looks like this: write.table(datatr$V1[data.chull],file="outr.txt", quote = FALSE, sep = "\t") In the outputfile (outr.txt) I have an "x" in the left corner and a new row with numbers for each column(1,2,3...).
