Hi I am having difficulty with eigen() on R-devel_2006-01-05.tar.gz Specifically, in R-2.2.0 I get expected behaviour: > eigen(matrix(1:100,10,10),FALSE,TRUE)$values [1] 5.208398e+02+0.000000e+00i -1.583980e+01+0.000000e+00i [3] -4.805412e-15+0.000000e+00i 1.347691e-15+4.487511e-15i [5] 1.347691e-15-4.487511e-15i -4.269863e-16+0.000000e+00i [7] 1.364748e-16+0.000000e+00i

Faraway's book titled "Practical Regression and Anova using R", with full text available online at: http://cran.r-project.org/doc/contrib/Faraway-PRA.pdf refers to a data set, stat500, which compares midterm and final grades. It can be used to illustrate similar concepts. A google search for faraway.zip will locate the actual data. --- Date: Sun, 15 Feb 2004 10:37:08 -0800

Hello! Are there any additional packages (besides "regex") I could use to incorporate regular expressions in my R code? I would be grateful for any tips or help you could provide! Yours, Ann Loraine

The following now occurs to me when I try to load lattice (R 1.7.1, debian stable): > library(lattice) Error in loadNamespace(i, c(lib.loc, .libPaths()), keep.source) : package `grid' does not have a name space Error in library(lattice) : package/namespace load failed I did an update.packages() as root recently. Any idea what's wrong? -- Edzer

Dear R-users, I found a strange problem working with products of two matrices, say: a <- A[i, ] ; crossprod(a) where i is a set of integers selecting rows. When i is empty the result is in a sense random. After some trials the right answer (a matrix of zeros) appears. --------------- Illustration -------------------- R : Copyright 2003, The R Development Core Team Version 1.8.0

Hi All, I was wondering if anyone here as successfully converted a package for windows to one that will work in Linux? What are the necessary steps if you have the source code? Thanks, Josh

Hi Thanks for that, but I still cannot confirm on ... sudo docker run -v $(pwd):/home/work/ -w /home/work --rm -ti rocker/r-ver:3.5.1 Could you please read the comments within the "Cairo Fonts" section of the ?X11 help page, in case that offers some explanation.

In plotmath expressions, R's degree symbol, e.g. shown by plot(1, main = parse(text = "1*degree*C")) has sunk to halfway the text line, instead of touching its top. In older R versions this looked much better. -- Edzer Pebesma Institute for Geoinformatics Heisenbergstrasse 2, 48151 Muenster, Germany Phone: +49 251 8333081

Thanks to Edzer and Roger, I can now plot with increased font sizes. However, jpeg still does not reproduce these, nor does it show up in high quality. What I would like to do is produce some highresolution jpegs. Any help would be appreciated Thanx Herry R2.4 on Mandriva 10.2 linux.

When running a = runif(10) class(a) = "foo" Math.foo = function(x, ...) { NextMethod(.Generic) } signif(a, 3) cumsum(a) I don't understand why cumsum strips the class, but signif does not. Both claim in the documentation that "These are generic functions: methods can be defined for them individually or via the ?Math? group generic." -- Edzer Pebesma Institute for

Hi I am seeking to understand why the methods package (to be specific `methods:::.findOrCopyClass` when called by `setIs` when called by `setClass`) emits a warning message such as ` class "SpatialLinesNULL" is defined (with package slot 'rgeos') but no metadata object found to revise subclass information---not exported?

List, In order to get rid of some old, unreadable S3 code in package sp, I'm trying to rewrite things using S4 methods. Somewhere I fail, and I cannot sort out why. In order to isolate the problem, I created two functions, doNothing<- and dosth, and both should do nothing. The issue is that in most cases they do nothing, but in some cases dosth(obj) changes the class of obj and breaks with

In the example: x = rep(c(0,0,1,1),4) y = rep(c(0,1,0,1),4) z = c(1,0,1,0,0,0,1,1,0,1,0,0,1,1,1,1) f = as.factor(c(rep("a",4),rep("b",4),rep("c",4),rep("d",4))) levelplot(z~x+y|f,data.frame(x=x,y=y,z=z,f=f)) I noted that the last ("d") plot remains empty. I guess the reason for this is that the values are constant (1), but I consider it more

G'day all, I am not sure whether I should file this as a bug report, but I thought that I should make the developers of R aware of the following feature: I have just installed R 2.0.0 and when I run "R CMD check" on the source of some packages, I noticed that the XXX-examples.ps file contains one page with two graphics overlaid. This seems to happen when the first graphic is

I wonder what is the default value for the argument 'cutoff' when not specified in the variogram.formula function of gstat. Computing variogram envelops within gstat, I am comparing the results obtained with variog in geoR and variogram in gstat, and it took me a while before understanding that the cutoff default value is not the maximum distance. Can Edzer tell us about it? All the

Consider the following examples: library(lattice) x = c(1,1,2,2) y = c(1,2,1,2) z = 1:4 levelplot(z~x+y,at=c(.5, 1.5, 2.5, 3.5, 4.5)) # correct levelplot(z~x+y,at=c(.5, 1.5, 2.5)) # ? The second plot is clearly incorrect. However, I don't know what correct behaviour is: ignore everything above 2.5 and issue a warning? Reject at values that do not cover the data range, and issue an

Suppose I'm author of a package on which quite a few other packages depend. When I submit to CRAN, I run R CMD check on it, Kurt does that too, and if things work out fine, it is accepted. When one or more of the packages that depend on it break because of my changes, however, hell breaks loose. I would like to extend my testing (currently: R CMD check pkg) to running R CMD check on all

I'm still trying to install R on my Irix machine. Now I have a new problem that crops up during the checks. I've found the root cause, and it's that R is returning zero for certain things for reasons I don't understand. 2.225073859e-308, entered directly into R, responds "2.225074e-308". 2.225073858e-308 responds "0".
