Dear list, Can anyone tell me how to obtain the rank of a sparse Matrix, for example from package Matrix (class dgCMatrix)? Here is an example of QR decomposition of a sparse matrix (from the sparseQR class help). library(Matrix) data(KNex) mm <- KNex$mm str(mmQR <- qr(mm)) Similarly, using the functions/classes from the relatively new MatrixModels package: library(MatrixModels)

Hi all, I'm trying to do some object-oriented programming in R using the R.oo package. Right from the start I encountered a strange (at least for me) problem. I define a new class/constructor based on the R.oo documentation. However the first attempt to create an object fails: === Code: === library(R.oo); setConstructorS3("MyClass",function(param) { print(param);

Hi, I am trying to fit a negative binomial model with a number of parasite tapeworms as response variable to geographical coordinates (actually preparing a trend surface before kriging). When I try an anova, I get warnings: > glm4.nb<-glm.nb(wb~X4+Y4+I(X4^2)+I(Y4^2)) > anova(glm4.nb) Analysis of Deviance Table Model: Negative Binomial(0.0463), link: log Response: wb Terms added

Hi Paul, We've been through this process ourselves for the Revolution R Open project. There are a number of pitfalls to avoid, but you can take a look at how we achieved it in the build scripts at: https://github.com/RevolutionAnalytics/RRO There are also some very useful notes in the R Installation guide: https://cran.r-project.org/doc/manuals/r-release/R-admin.html#BLAS Most packages do

Thierry, I have this: if (require(MatrixModels) && require(Matrix)) { X <- model.Matrix(Terms, m, contrasts, sparse = TRUE) in my function rqss() I've tried variants of requireNamespace too without success. If I understand properly model.Matrix is from MatrixModels but it calls sparse.model.matrix which is part of Matrix, and it is the latter function that I'm not

Thanks. This should be resolved in R-devel(r72788) and R-patched (r72789) Best, luke On Mon, 12 Jun 2017, Berend Hasselman wrote: > > > In this email to the R-help list: https://stat.ethz.ch/pipermail/r-help/2017-June/447474.html > and in this question on Stackoverflow: https://stackoverflow.com/questions/44486643/nleqslv-memory-use-in-r > > Andrew Leach has raised a question

Good afternoon, A strange one - library(rJava) works for root but not for user sean On 64-bit Ubuntu 9.10, using R as root (sudo -i), I can say library(rJava) and it works fine with no error message of any kind. But logged in as myself user "sean", it can't start... sean at SeansPC:~$ R --no-save --vanilla R version 2.10.1 (2009-12-14) Copyright (C) 2009 The R Foundation for

In a model with a loop within a function he has experienced continuously increasing memory usage by package nleqslv

Dear R-devel: The Cluster administrators at KU got enthusiastic about testing R-3.2.2 with Intel MKL when I asked for some BLAS integration. Below I forward a performance report, which is encouraging, and thought you would like to know the numbers. Appears to my untrained eye there are some extraordinary speedups on Cholesky decomposition, determinants, and matrix inversion. They had

I'm having trouble with R CMD check of my quantreg package. All is well until I get to: checking running R code from vignettes ... ?rq.Rnw? ... failed ERROR Errors in running code in vignettes: when running code in ?rq.Rnw? when I see a snippet from the vignette code and then: Loading required namespace: MatrixModels When sourcing ?rq.R?: Error: could not find function

This note is to r-devel rather than r-announce because it notes an experimental package that addresses issues that intersect with broader developmental issues in R. I have posted the package cremo = Comparative REndering of Modeling Outputs for retrival at http://www.biostat.harvard.edu/~carey/cremo.html This package addresses the problem of assembling and rendering results of multiple

Dear all, I have run into a problem when running some code implemented in the Bioconductor panp-package (applied to my own expression data), whereby gene expression values of known true negative probesets (x) are interpolated onto present/absent p-values (y) between 0 and 1 using the *approxfun - function*{stats}; when I have used R version 2.8, everything had worked fine, however, after updating

And let's also spell things properly! Like 'internationalisation' ...'Weasels have got into your phone system' instead of 'gotten into your phone system...' And 'please press the hash key..' instead of 'pound key' There should probably be en_uk, en_us, en_ca, en_za, en_nz, en_oz, en_ie and en_in etc to allow each English-speaking country to localise

I'm hoping someone can help me out with this... I've been running the Wine package in Debian/Woody for quite a while now, and have been able to run most of the windows programs I want to.

Hi all, In a simulation context, I'm applying some my function, "myfun" say, to a list of glm obj, "list.glm": >length(list.glm) #number of samples simulated [1] 1000 >class(list.glm[[324]]) #any component of the list [1] "glm" "lm" >length(list.glm[[290]]$y) #sample size [1] 1000 Because length(list.glm) and the sample size are rather large,
