Dear R team I have a problem with the installation of the RCOR package; any time I try to install it I get the error message: Error: package 'ROCR' was built before R 2.10.0: please re-install it. What can I do to solve this problem? Thank you Kind regards Dr. Matteo Pettinari Senior Assistant Cardiale Heelkunde matteo.pettinari@uzleuven.be<mailto:matteo.pettinari@uzleuven.be>

In my package, I create a new method for plot with the following signature: setMethod("plot", signature(x="marrayNorm", y="formula"), plot.ma) where marrayNorm is a class defined in the marray package. After building and installing my package, I get the following warnings when I load my package (with library(maVis)): Warning messages: 1: In the method signature

Martin Maechler has suggested that I post this comment to r-devel. It was originally posted to bioconductor. --------------------------------- I'd like to raise the issue of a capitalization convention for naming objects in R. Almost everything in R used to be lowercase but recently there is increasing use of mixed upper/lower case to define names. There is potential for using the

Hi all, is it possible to modify the way a graph obtained through image(graphics) is filled, I mean starting filling the graphical matrix by row from the upper-left rather than by the lower-left cell... In many cases, it can be usefull to have a representation of the data spatialy corresponding to a real support, as it is the case with the function image(marray) from Bioconductor packages, which

Dear all, I want to see if the treatment of an animal with a specific compound has an effect on the expression of certain genes. Though my question is based in biology, it really is all about how to deal with the standard deviation in normalised data. I have three groups of animals; untreated, treated with placebo, and treated with a single concentration of the compound in question. Gene

Dear list, I would like to generate random numbers from a Voigt distribution, hopefully in a way as simple as getting random numbers from a normal distribution with 'rnorm'. Is there any package to do this? Speed is an issue in this application. Or, as the Voigt distribution is a convolution of a Gaussian and a Lorentzian, can I simply combine random numbers from rnorm and rcauchy in some

Dear List, My data consist of nine columns and about 50,000 rows.

Hello! When I use the functions rma() or justrma() in the Bioconductor affy package, the standard errors for the expression estimates computed by the function se.exprs() is a matrix of NA's. I am wondering if any of you have encountered this problem and if there is a solution. Any help would be appreciated. Thanks, Karthik. [[alternative HTML version deleted]]

Hi, I've spent a while scrabbling around at this problem, to no avail. I'm sure there /should/ be a simple answer... I have a large (14 million rows) data set, with two columns. Each row contains the number of times an individual moved, and the distance that individual moved in total. I would like a figure where the colour indicates the density of points, rather like this one my

Dear R Users, Are there any packages in R which carries out a normalisation to variables as follows: - find the empirical distribution function, using perhaps ecdf - use the empirical distribution function to transform the variables into a series between 0 and 1 - use this series to map the variables into the normal distribution function, using qnorm - perform a regression on the transformed

Hello, I'm a french student working on a project concerning cDNA microarray. I've chosen to work with R and use the marrayClasses, marrayInput (...) packages. First, when I enter "library(marrayInput)", R warns me about a missing package called "utils" but I can't find it anywhere. Normally this package is installed when you install "base" package.

What''s the best way to exclude ActiveRecord in Rails3? In Rails2, one could just do: *config.frameworks -= [ :active_record ]* in the configuration block in environment.rb. Is it possible in Rails3?

Hi, I''ve been trying to develop a Rails gem/plugin with generators for Rails 3. I first had a separate gem project with a gem statement in my Gemfile with a :path option to point at it. But then I had to run $ rake install on each change in my gem to have Rails pick up on it. I have now instead put my generators inside RAILS_ROOT/lib so they are easier to test/develop. lib/generators -
