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

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 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
