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

I would like to build a package for the HT HG-U133+ PM arrays from affy, but I can't find any good documentation on how to go about it. Naively using makecdfenv's make.cdf.package() causes R to seg-fault. I'm unfamiliar with the CDF format as such, but I'm guessing that it's changed somewhat because the PM arrays no longer have P/A and mismatches. I'm looking to build

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

Hello, Just a quick message to say that, ------------------------------------------------------------------------ ------- when choosing (with or without the tcltk window) "Bern 1 (swiss)" as CRAN mirror to install a package (function install.packages) for R-2.5.0, the list of available packages for osx seems not complete: AMORE, AdaptFit, AlgDesign, AnalyzeFMRI, SemiPar,

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

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-people, I hope asking this is not too cheeky, but I do have a R Problem. I hope that some of you like to play around with R and can help me. Its like this. I have several plant species (A,B,C) and 10 replicates per species. 5 plants per species are damaged, 5 not. I let a caterpillar feed on each plant and measured the growth of the caterpillars on control plants (CR) and on damaged

Dear R users, I would like to know if there is a way in R to execute a post-hoc test (factor levels comparison, like Tukey for ANOVA) of a non-parametric analysis of variance with kruskal.test() function. I am comparing three different groups. The preliminary analysis using the kruskal-wallis-test show significance, but I still don''t know the relationship and the significance level

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

Hello everyone, my workplace has gotten the idea of centrally maintaining a file in ssh_config syntax so that employees do not need to discover every new machine and configure it on their own. Since it's a case of "let's get started now, and properly think it through later", right now, a typical entry might look like > Host [product]-[Customer] > Hostname

Hi List, I'm trying to install aroma.affymetrix, which depend on many packages, affyio is one of them. The task is done on 32-bit Linux without problem. The same task was done on Solaris 9 with R-2.5.1 without problem. Following is the error message when installation affyio. I did try to put a file stdint.h I got from the web in the path, but got more error messages. Jun root@biostatsun1
