...across the following problem while working with a dataset, and wondered if there could be a solution I sought here. My dataset consists of information on 402 individuals with the followng five variables (age,sex, status = a binary variable with levels "case" or "control", mma, dma). During data check, I found that in the raw data, the data entry operator had mistakenly put a "0" for one participant, so now, the levels show > levels(status) [1] "0" "control" "case" The variables mma, and dma are actually numerical variab...

Hello, I want to build an application where i have client and server. I need to exacute commands with XM-RPC. I can get all this working, following the howto''s in wiki and main website.

...as vitamin B12 went down methylmalonic acid went up. This is as expected for people with diagnosed vitamin B12 deficiency but these patients had rather high vitamin B12 concentrations and most people wouldn't believe them to be vitamin B12 deficient. We expected the relationship between B12 and MMA to be nonlinear in that when B12 was high enough, MMA wouldn't increase. We have modeled the response in Genstat using the new REML facility and fitted a spline which shows the expected asymptote and also a 1.st order time series. In R I have fitted a Gee model of the marginals also with a firs...

There was some interest in the commands for creating an HTML file of 3D graphics that can be shown with a Java applet. Looking at things I discovered (of course) that I should really clean up quite a few things before releasing it for real. I hope to do some of that this weekend. In the meanwhile, here are a couple of pointers to...

Hi All, I'm familiar with bwplot() in lattice package. Is it possible to get such a boxplot using lattice package: http://www.reading.ac.uk/ssc/publications/graphics/mma-fig1.gif instead of the following default: http://media.wiley.com/wires/WICS/WICS22/mfig005.gif My aim is to get a compact boxplot for publication. Having legend can help because otherwise x-axis labels are repeated for each rectanglular box. Thanks, Peng Cai [[alternative HTML version delete...

...I would like to make a simple combination where, instead of scalars, i would like to combine vector, in order to form matrixes. In other words, i have nineteen 6-items vectors (for example coef1-coef19), that i would like to combine in n!/k!(n-k)! 6x6 matrixes. I tried with a code like this mma <- combn(c(coeff1,coeff2,...,coeff19),function(x) matrix(x,6,6)) but i think that R doesn't recognize that these are not scalars. In fact the error is: Errore in matrix(r, nrow = len.r, ncol = count) : invalid 'ncol' value (too large or NA) Inoltre: Warning message: In combn(c...

Say I have an hosted application which allows the user to use their own domain name (company.com) to access it, and that application must be accessed over SSL, how do you go about our SSL certificate not being registered to their domain. Sure the connection will be safe but the browser will pop up a warning saying the certificate is invalid for this domain. I dont think this problem occur

I''m interested in making a low volume rails application very available. This means that I would like to have an alternate server for those times when the primary server is unavailable for whatever reason. Virtual private servers are fairly inexpensive so one could have a rails application on 2 different vps systems (not on the same server, possibly not even in the same city).

Hello R users, I am reading data into R from RMySQL or SQLite databases which are in Spanish language. I am using RMySQL library and function dbReadTable but I could not get characters with ñ and tilde, instead R does put ?. In the past I could manage it modifying the R options as (using windows): op <- options() op$encoding <- "iso-8859-1" options(op) but now in ubuntu it did

Dear David, > I managed to install Sage on Windows (via a Linux VM), but I cannot find any documentation on how to use R from Sage. Maybe I > should use the web interface of Sage to avoid having to install R on the VM. In the Sage command line, you can type sage: r? to get some very basic info, and sage: r.[tab] to get various commands. This part of the interface still needs some work, though it suffices (particularly via r.eval()) for many needs. You do NOT need to reinstall R; a full copy of R (with all recommended packages...
