similar to: No fonts control on Cairo in batch mode

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

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

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

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

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 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 <-

Dear all, 'Apply' is a great thing for running functions on rows or columns of a matrix: X <- rnorm(20, mean = 0, sd = 1) dim(X) <- c(5,4) apply(X,2,sum) Is there a way to use apply for excluding rows or columns from a matrix to run functions on the remaining rows or columns? I know, I could do this with a 'for' loop, but 'apply' would be much easier and

Hi, I have two networks, users and servers connected via vpn (ipsec). Both internal networks. The routing is fine and connections work both ways. Accordingly both networks have a firewall each which faces the internet and they create the vpn link between each other. Both firewalls have only one external IP (if they had more, I wouldn''t be asking). The servers network''s

Dear all, I was looking for methods in R that allow assessing the number of significant principal coordinates. Unfortunatly I was not very successful. I expanded my search to the web and Current Contents, however, the information I found is very limited. Therefore, I tried to write code for doing a randomization. I would highly appriciate if somebody could comment on the following approach.

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
