similar to: No fonts control on Cairo in batch mode

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 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,

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 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

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

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 all, I would like to announce the availability of a new package on CRAN: RNetCDF: R Interface to NetCDF Datasets This package provides an interface to Unidata's NetCDF library functions (version 3) and furthermore access to Unidata's udunits calendar conversions. The routines and the documentation follow the NetCDF and udunits C interface, so the corresponding manuals can be

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...). I just want the values in my file. What should I change in

hello there, I ` m a newbie in R so please excuse my maybe simple question! I have several (the number of the files changes) textfiles. Each textfile contains one column with 3 rows (3 numerical values). I want to combine each file with another file and create new textfiles which then contain 2 columns with 3 rows. How can I do this in R? Do I have to use cbind? How Do I use cbind for my

Dear all, I am interested in correctly testing effects of continuous environmental variables and ordered factors on bacterial abundance. Bacterial abundance is derived from counts and expressed as percentage. My problem is that the abundance data contain many zero values: Bacteria <-

Hello I'm trying to calculate 2d confindence bounds into a scatterplot using the function "kde2d" (package MASS) and a contour plot.

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 R users who might like to use the package RNetCDF on Fedora Linux: Fedora (versions 4 and 5) users might have noticed that the default install of the netcdf and netcdf-devel packages from the Fedora Extra archive is inconsistent with the R package RNetCDF. The attempt to install RNetCDF results in a failure in the configure stage because the header & library info for netcdf cannot

just a suggestion.. get www.xenserver.org install a xen server. get xen convertion tools. http://www.citrix.nl/downloads/xenserver/tools/conversion.html and migrate the linux on hardware box to Xen server. from here you can also export to OVF/OVA package or XVA file. the OVF can be inported in virtual box.. but i do everything with xen server. greetz, Louis

Hello, I'm running running samba 3.0.14a on a Gentoo 2005.1 Linux box. I have first set up Gentoo 2005.0 with Samba 3.0.10 (I think) and everything went fine. After an update to Samba 3.0.14a it will not work as it should. I'm running winbindd and samba with the following configuration: [global] workgroup = CDE server string = %h server (Samba %v) security =

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

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 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:
