Hi, Before I write code to do it does anyone know of code for fitting mixtures of multivariate-t distributions. I can't use McLachan's EMMIX code because the license is "For non commercial use only". I checked, mclust...

Hi If you have a first order effect like that then you can try fitting a linear model to the data and the use the residuals for checking autocorrelation. This will introduce some bias but it is small relative to...

Hi, >From the sound of this it is time to grit my teeth and get the quadtree code working for maptools. That should translate for a polygon list from Spdep and allow calculation of adjacency matrices in R for moderate...

Hi, Is there a command that will give the total size of an R object in bytes? thanks Nicholas -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un...

Hi, I changed INTEGER(getAttrib(shape,mkChar("nParts")))[0] to INTEGER(getAttrib(shape,mkString("nParts")))[0] and now it works fine.

Hi, I was just able to try this on a windows xp machine using R-2.5.1. gnls exits gracefully with an error so maybe this is a problem with my R installation. If so sorry to bother everyone...

Hi James, You can try the hexbin package at www.bioconductor.org. Do the following bin<-hexbin(x,y) ## This will give you hexagonal bins of the data binsm<-smooth.hexbin(bin) plot(binsm) This is an approximation to what...

Hi, No, as it says, it is a C++ port of the java topology suite. JTS is a nice library, it just happens to be in java (oh well, I like real coffee). I do not think it is the...

Hello, I am writing a set of functions to do prediction and calibration intervals for at least the subset of selfstarting models if not some more general ones. I need to be able to extract the varFunction from a fit...

Hi the following example I think demonstrates the inconsistency > f<-function(x) x > length(f) [1] 1 > is.na(f) [1] FALSE Warning message: In is.na(f) : is.na() applied to non-(list or vector) of type 'closure' The...

Hi here are the updates in hexbin Thanks to some help from Deepayan Sarkar, hexagon binning functions now work with grid. Implemented so far are hexbinplot (xyplot with hexbins) and hexplom (splom with hexbins). There are several panel functions for...

Hi, Does anyone have any experience porting Ratfor to fortran. I have gotten the ratfor preprocessor working and if I compile the ratfor code directly and dynamically load into R it seems to work (using g77 on RH linux). However...

Hi Frank, Thank you for the correction, I don't work in clinical, so good you keep me honest. Nicholas On Sun, 11 Jan 2009 09:21:23 -0600, "Frank E Harrell Jr" <f.harrell at vanderbilt.edu> said: > Nicholas...

Hi, I had some excel files that I needed to read into R, there were alot so I didn't want to do them by hand in gnumeric. I tried all the recommendations in the data import/export manuals, including...

Hi, Debby Swayne is working on a new version of xgobi (now called ggobi). I have been working with her and we have succeeded in compiling (and running) the preliminary version native on windows. No more emulation! all it needs...

Hi again, I took a look at maptools code and shapelib last night. It should not be hard to modify to create and write shapefiles. I think I never developed it in maptools because I never really thought of R...
