Dear list, My apologies if a solution / explanation to this already exists on the list, but it is difficult to assign it to a certain keyword. test<-c(1:3) testfct <- function(x) {test[1]<-100} test [1] 1 2 3 testfct(1) [1] 1 2 3 Basically, I would like to write data into an external table that the function does not know. Why is this not working / what alternatives exist? Thanks,

hi, this may be trivial, but we can't seem to find anything adequate, (although there is a work around with match() ). We are looking for something along the lines of plot(table1[table1$var2==or("a","b","c","d"),"var1"]) would be handy, with the potential or() function leading to what plot(table1[table1$var2=="a" |

Hello, anyone got an idea on how to use stl() so that the remainder eventually becomes white noise? i used stl repeatedly but there is autocorrelation in the remainder that i can't get rid of. os: linux suse9.3 ------------------------------------------------ Sebastian Leuzinger Institute of Botany, University of Basel Sch??nbeinstr. 6 CH-4056 Basel ph 0041 (0) 61 2673511 fax 0041 (0)

hello, has anyone come across the following rather mysterious problem: when pasting large bits of code (100 and more lines) into the R console with the central mouse button (under linux), only part of the code is pasted, and the text interrupts somewhere arbitrarily. It does not happen when smaller bits are pasted subsequently. I use linux suse 9.3 with the latest version of R

Hello A very short question: Using multiple plots with par(mfrow=c(3,3)), how can I get R to indicate one common y- and x-axis label? I tried to use text() in par, but this is then overwritten when I plot the graphs. -- Sebastian Leuzinger Institute of Botany, University of Basel Schönbeinstr. 6 CH-4056 Basel Ph. 0041 (0) 61 267 3511 fax 0041 (0) 61 2673504 email: Sebastian.Leuzinger@unibas.ch

Hi I run suse linux 9.1 and I installed MySQL server, client, devel, bench. DBI is installed, when I try to install RMySQL I get an error saying, that libz is missing. (paths to libs were set:export PKG_CPPFLAGS="-I/usr/include/mysql/" export PKG_LIBS="-L/usr/lib/mysql/ -lmysqlclient") so my question: where do I get the libz files (are these mysql files? if yes, why were

Hello Trying to install the MySQL package, I get the following error. The help archive contains something on this issue but did not help. I work on linux suse 9.3 Configuration error: Could not locate the library "libz" required by MySQL. The library libz however is not on any mirrors I checked. ------------------------------------------------ Sebastian Leuzinger web

dear list while installing the package rimage, i get the error message checking jpeglib.h usability... no checking jpeglib.h presence... no checking for jpeglib.h... no configure: error: Sorry, can't find jpeglib header ERROR: configuration failed for package 'rimage' although i have installed jpeglib as required. does R not find this library? but why did it find the fftw library

hello, is R able to suppress tick labels (not tick marks)? i know there is a way around this with axes=F and then draw new axes, but it would be easier to suppress them in the first place. -- ------------------------------------------------ Sebastian Leuzinger Institute of Botany, University of Basel Sch??nbeinstr. 6 CH-4056 Basel ph 0041 (0) 61 2673511 fax 0041 (0) 61 2673504 email

it must be terribly simple, can someone quickly help me? test <- data.frame(y=c(1:10), x=as.factor(c(rep("a",5),rep("b",5)))) how can i change the factor labels from "a" and "b" to for example "u" and "v"? i don't succeed with factor() thanks a lot ------------------------------------------------ Sebastian Leuzinger

Dear all I imported a Stata .dta file with the read.dta-function from the foreign-package. The dataframe's dimensions are > dim(d.apc) [1] 15806 1300 Importing needs up to 15 min and calculations with these data are rather slow (although I subset the data before starting analyses). My questions are: 1. Has someone experiences importing Stata files (alternatives to read.dta) ? 2.

Dear R-list member, I'm using the function pmnorm() (-->library(mnormt)) within a for-loop. Certain parameter values leads to an error message: "(In sqrt(diag(S)) : NaNs produced, In sqrt(1/diag(V)) : NaNs produced, In cov2cor(S) : diag(.) had 0 or NA entries; non-finite result is doubtful)" obviously because "NaNs" were produced. Is it possible to tell R that it

Hi everyone I have the following problem: My dataframe has 3 variables: ID, Year and and an outcome variable. The dataframe contains repeated measurements because the subjects filled out a questionnaire every year. The time span covers 2 years. Now I want to check if there is a significant change in the outcome over the 2 years with a paired wilcox.test. The problem: Not every subject

Dear R-helpers, I try to perform glm's with negative binomial distributed data. So I use the MASS library and the commands: model_1 = glm.nb(response ~ y1 + y2 + ...+ yi, data = data.frame) and predict(model_1, newdata = data.frame) So far, I think everything should be ok. But when I want to perform a glm with a subset of the data, I run into an error message as soon as I want to predict

Hi all Maybe a stupid question, but I'm not able to figure this out from the manpage nor from the HOWTOs... How can I force a user to change his password at next logon? I tried: # pdbedit -P "user must logon to change password" -C 0 -u username # pdbedit -u username -P "user must logon to change password" -C 0 # pdbedit -P "user must logon to change password"

Dear Torsten, dear samba list reader Three days ago I switched our domain from a NT 4 domaincontroller to Samba-OpenLDAP, controlled by a Debian Sarge system.

Hi list I just compiled 3.0rc1 on Solaris 9 (UltraSparc IIe) with gcc 3.3.

Hi everyone I'm using Tukey HSD as post-hoc test following a lme analysis. I'm measuring hemicelluloses in different species treated with three different CO2 concentrations (l=low, m=medium, h=high). The whole experiment is a split-plot design and the Tukey-function from the package multcomp is suitable for lme-analysis with random factors. The analysis works fine but I get a non

Hi R help list I'm simulating logistic regression data with a specified odds ratio (beta) and have a problem/unexpected behaviour that occurs. The datasets includes a lognormal exposure and diseased and healthy subjects. Here is my loop: ors <- vector() for(i in 1:200){ # First, I create a vector with a lognormally distributed exposure: n <- 10000 # number of study subjects

Hi all, is there an easy way to build up a data frame by sequentially adding individual rows? The data frame consists of numeric and character columns. I thought of rbind, but I ended up with numeric values for the character columns. Pascal
