Greetings, I have "inherited" a cDNA macroarray dataset that is structured as follows. Three different stressors were tested. For each stressor, there are two treatments (control and stressed). For each treatment, two biological replicates exist, and these are paired (i.e., there is a stressed array for colony A and a control array from this same colony). For one of these samples,

I have some data that is dwarfed by one large cluster. I came across a paper titled "A New Partitioning Around Medoids Algorithm" (van der Laan, Pollard & Bryan, 2002) http://www.bepress.com/ucbbiostat/paper105/ that describes PAMSIL and PAMMEDSIL that look as though they might be more appropriate for the data I have. There does not appear to be much out there which is describing itself by these names. So any help would be appreciated. Tom ______________________________________...

Hi folks, is it possible to read more things about R behavior in multiprocessor / multihost environment ? Is there any distributed computation project associated to it ? Laurent

I need to rewrite a software in R, that runs on a cluster. I thought Rmpi will be good for me but I can't find any help other than the Rmpi-manual that actually only describe the functions in the Rmpi package. Can someone point me to some usefull guide? For example, I would like to run a for-statement on several processors (a subset of the statement on each processor) but I can't figure

...ion of a scientific result, there is every reason for the data to be part of that publication. The Gentleman and Lang 2004 paper "Statistical Analyses and Reproducible Research" takes this further still, making a compelling case for opening the analysis to ready view. (http://www.bepress.com/bioconductor/paper2/ ) How else can critics know what analysis was done, and whether the data do really support the claimed conclusions? As I see it, the first recourse should be use of archives that individual communities may establish. Instructions on how to input the data into R wo...

According to the documentation at http://docs.puppetlabs.com/puppet/2.7/reference/lang_conditional.html#if-statements, you can test for truth with syntax like this: if $is_virtual == ''true'' { AFAICT that''s not the case. The quotes around ''true'' make the comparison always fail. Here''s my test case class users {

I just discovered the great piece of software that is available with the survey package. Many thanks and 'Hats off' to Thomas Lumley. While package survey covers analysis of features of objects sampled (in clusters, strata) I could not find analysis of features of repeated relationsships between sampled objects (in clusters, strata). My understanding is that it is not adequate to treat

Hi, In support of reproducible research at my Institute, I seek an approach to re-creating the R environments in which an analysis has been conducted. By which I mean, the exact version of R and the exact version of all packages used in a particular R session. I am seeking comments/criticism of this as a goal, and of the following outline of an approach: === When all the steps to an workflow

Dear all, Can I do a permutation test if the number of individuals in one group is much bigger than in the other group? I searched the literature but I didin´t find any assumption that refers to this subject for permutation tests.

Hi All I am really very interested in starting to use R within our company. I particularly like the open source nature of the product. My company is a medical research company which is part of the University of London. We conduct contract virology research for large pharma companies. My question is how do we validate this software? I wonder if anyone else has had the problem and might be able to
