Dear R-nautes, I installed the 2.7.1 version of R and found it is not possible to modify graphical parameters with par(). for example; > par(mfrow=c(2,2)) Error in c(2, 2) : unused argument(s) (2) > par$mfrow NULL Does any one know what is the cause of this problem?

Hi, I would like to get guidance as to how to write code in R that can deal with the following situation: v1 is a vector containing a sequence of numbers (Ex. 1:10) I want to store the sequence of numbers resulting from multiplying the first and the second element in the vector, then the product of the 1st, 2nd and 3rd, then 1st,2nd,3rd and 4th and so forth until all the elements in the

Dear Rs, Is it appropriate to include several phenotypes (binary outcome variables in genetic analysis) in a logistic regression model that explores the effect of a few genotypes (factors)? If so, wouldn't there be an issue with multiple testing? Thanks for your opinions, -- Fabio Sánchez, MD, MSc, PhD Unit of Dermatology and Venereology Department of Medicine Karolinska Institute SE-17176

In case there are users of the TeX macro package ConTeXt on this list, they may be interested to know that it is now possible to include R code in a ConTeXt document and have the code evaluated while compiling. The inverse of Sweave, as it were. The advantage is that there is then only one file to keep track of (.tex vs .rnw and .tex), while a drawback is speed, since each code snippet is

Dear list! I have run into a problem that seems very simple but I can't find any solution to it (have searched the internet, help-files and "An introduction to R" etc without any luck). The problem is the following: I would like to create a data.frame with two components (columns), the first component being a matrix and the second component a vector. Whatever I have tried so far, I

Hi, I''ve created some extensions to script.aculo.us InPlaceEditor, allowing the use of either server-driven, or local autocompletion. I''ve also created new helper methods in Rails for this functionality. My question is, is there any interest that I package this and make it available as a plugin, or something like that?

Hi CAS is a centralized authentication service, and the cas_auth filter can be installed to automatically make your web application authenticate against a CAS server. The SVN path to the plugin is http://svn.ki.se/rails/plugins/cas_auth and a homepage with some information can be found at http://opensource.ki.se/casauth.html For use, just install the plugin in your application and set

Hi I''m in the process of deciding how a plugin should be designed to make configuration as easy as possible. Right now I require the plugin from init.rb, and set some configuration options (as class attribute accessors) from environment.rb. Then I tried setting these from environments/development.rb instead, and to my surprise this didn''t work. It said the class in question

Hi Rails AJAX controls are very handy, and the InPlaceEditor is probably one of the easiest and most neat of them all. But, it doesn''t do autocompletion. I''ve rectified that situation. The plugin provides a few new helpers and a new JavaScript-file that extends the Ajax.InPlaceEditor with local and remote Autocompletion features. So, just install the plugin, include the

Dear List, I am using the bioconductor package Category to do some gene enrichment analysis, and usually save my KEGGmnplot's using a dev2bitmap command. This has worked just fine, until suddenly earlier today I got this error-message: > dev2bitmap("04610_080721.jpg",type="jpeg", height = 10, width = 10, res = 200) Error in dev2bitmap("04610_CSF080721.jpg",

Can anyone suggest a good non-parametric test, and an R implementation of the test, that allows for two or more factors? Wilcoxon signed rank allows for only one.

I would like to announce my plugin Swedish Rails. Rails provide many goodies and helpers for you, but some of these are dependant on your user interface being in english. Date controls, for example. Pluralization is another. And have you ever tried to capitalize a string with Swedish letters in them? Then you know it doesn''t work that well. Until now, that is. You install this

Hello, I was hoping for some advice on improving a barplot. Below is the syntax I have used. I wanted to do two things differently How would I alter the syntax so that (a) the y-axis finishes at 25 and not 20, and (b) 'past ideation' and 'pastwk ideation' are coloured blue and 'past attempt' & 'past wk attempt' are coloured red ? I was also curious as to

I have been running R CMD check for the first time on of our own packages, which otherwise builds, installs and runs just fine. The package depends on package akima and suggests package multtest; suggesting multtest is indicated because a) it loads a lot of other Bioconductor packages, very slowly, and b) it is only needed for one specific subroutine, which executes require(multtest)
