I apologize in advance for posting a question not related to R. I need references to papers that use multiple linear regression in an industrial application and also in a biological experiment. This is aimed to biologists/chemists (non-statisticans) so if anyone has written a brilliant paper where the use of multiple regression is important and also understandable to people with little knowledge of statistics and you like to be cited, please email me the reference off the list. To show the wide range of application I would like to have an e...

...cially non-parametric and semi-parametric methods for complex survey and longitudinal data? Is there a book that someone recommend that covers these topics with R (or Stata) examples? My web-searches have not resulted in much except that these seem to be actively researched topics by some statisticans working on theory --- no packages mentions of software were found in the few (I recall only one) empirical examples found.

Hi *, is there a way to obtain some kind of p-value for a model fitted with RMA using the lmodel2 package? I know that p-values are discussed and criticized a lot and as you can image from my question I'm not very much of a statistican (only writing my bachelor thesis). As fare as I understood the confidence interval statistic correctly, a coefficient is regarded as statistically significant if the corresponding CI does not include 0 (null hypothesis). But can I obtain some kind of a p-value to say that it is highly significant...

...enchmark article (http://www.sciviews.org/other/benchmark.htm) I have been more interested in making the R code itself more efficient. I would like to find more info about this. I have tried to mail the contact person for the benchmark, but I have so recieved no reply. I am not an R programmer (or statistican) so I do not know R well. I am looking for some advice about writing fast R code. What about the different data types for example? Is there some good place to start to look for more info about this? Thanks for any pointers Lennart

Hi, Could someone please suggest where I might find some instructions / tutorials / FAQs that describe how to create a frequency distribution and cumulative frequency distribution in R using different class withs. I have about a 2-million observations (distances between points ranging from sub-millimetre to about 400km, and I want to get a feel for how they are distributed). I'd like the

...olons and semicolons, etc. More generally, one could use the file extension or if available the unix 'file' command to evaluate the filetype if it is non ascii. I think it should not be very complicated to get a very high accuracy for detecting formats. For most datafiles it is for a human statistican easy to see the format of the file by looking at a fragment, so it should be possible to capture these rules in some code. It would be nice to have something like a read.magic() function that reads a datafile using the appropriate command, regardless of whether the user supplied an csv1, csv2, tab...

Hi The Food and Agriculture Organization of the United Nations (FAO), based in Rome, is in urgent need of an econometrican/statistican. The candidate will be required to provide in the absence of primary information model-based estimates of elements of utilization that enter our Food Balance Sheets (see http://faostat3.fao.org/home/index.html#HOME). We are therefore looking for two candidates who meet the following profile: -Eco...

Dear R People: I am using R for teaching purposes in a large classroom. Each computer has its own copy of R. However, every once in a while, about half of us will get thrown out of R, for no apparent reason. By the way, it has happened in other classrooms as well. Has anyone else run into this, please? If so, how have you solved this problem, please? Thanks in advance! R for Windows

Hi everyone, Could somebody explain to me what is the package/function for classification analysis. I am performing analysis of music files in the form of MIDI files. I end up with about 750 dependent variables from the analysis, I also have a number of independent/grouping variables that I set manually. What I would like is to be able to predict which group a particular MIDI files belongs to
