quantreg and sparseM will not load
I have recently started using R and want to use the quantreg (and
sparseM) packages.
I downloaded the .tar files for each, and placed the subsequent
folders into the library folder in the frameworks/R.framework/
resources/library folder with all the other packages.
When I try to load either package from the package manager window I get:

Loading SparseM on Win2K
I'm having trouble loading the package SparseM in R 1.8.1, OS = Windows
2000.
Installing appeared to go well; I saw no error messages, html documentation
was installed, and "installed.packages()" lists SparseM among the installed
packages.
When I try to load the library, however, I get the following:

Matrix / SparseM conflict (PR#8618)
Full_Name: David Pleydell
Version: 2.2.1
OS: Debian Etch
Submission from: (NULL) (193.55.70.206)
There appears to be a conflict between the chol functions from the Matrix and
the SparseM packages. chol() can only be applied to a matrix of class dspMatrix
if SparseM is not in the path.
with gratitude

How to use "SparseM-conversions" to convert a dCgMatrix into a matrix.csr ?
Hi all,
I want to transform a dCgMatrix from package Matrix into a matrix.csr from
package SparseM, and I found out this link :
http://stat.ethz.ch/R-manual/R-devel/library/Matrix/html/SparseM-conv.html
But there's no informaion about usage/description/arguments, so how do I
use this SparseM-conversions method ?? Is it a function ??
By the way I already tried function: as.spam.matrix.csr

Help with 'annotation' in GOHyperGParamsClass
Dear cateGOry experts,
hyperGTest documentation states that YEAST cannot be used as 'annotation'
when evaluating gene ontology representation status for a given set of

Because I am using a custom print I believe I need to create my own data

Rgui.exe cannot be set as default program under Vista wtih R2.10.1
Dear moderators,
when I installed the latest version of R (R2.10.1) under Microsoft Vista (service pack 2), I ran into problems associating Rgui.exe with .RData files. On doubleckicking such files in explorer, they open in a Rterm window. Trying to associate Rgui.exe with the Rdata files via control panel / default programs does not work - Rgui is not added to the list of recommended programs. I

Matrix: Help with syntax and comparison with SparseM
Hi,
I am writing some basic smoothers in R for cleaning some spectral data.
I wanted to see if I could get close to matlab for speed, so I was
trying to compare SparseM
with Matrix to see which could do the choleski decomposition the
fastest.
Here is the function using SparseM

issue with varSel.svm.rfe in package MCRestimate
Hello all,
I would like to perform SVM-RFE (Guyon et al. 2002) in R and have only found
one implementation of this algorithm. The function belongs
to the MCRestimate package but when I try to use it I encounter a problem
- the function appears to be missing a required package or other function
that I simply cannot find available anywhere.

Initializing SparseM matrix matrix.csc
Hi!
Would like to initialize a huge matrix.csc (Pacakge SparseM) with all elements 0
and afterwards set a few alements nonzero.
The matrix which I like to allocate is so huge that I can not use
A <- matrix(a,n1,p)
before:
A.csr <- as.matrix.csc(A)
because I can not allocate such a huge matrix A.
But I believe that the much more memmory efficient model in case of csc matrix should do it for

Predict using SparseM.slm
Hi,
I am trying out the SparseM package and had the a
question. The following piece of code works fine:
...
fit = slm(model, data = trainData, weights = weight)
...
But how do I use the fit object to predict the values
on say a reserved testDataSet? In the regular lm
function I would do something like this:
predict.lm(fit,testDataSet)
Thanks

Indexing with sparse matrices (SparseM)
Hello,
I'm working with a very large, very sparse X matrix. Let csr.X <- *
as.matrix.csr*(X) as described by the SparseM package.
The documentation says that "Indexing .... work just like they do on dense
matrices". To me this says that I should be able to perform operations on
the rows of csr.X in the same way I would on X itself. E.g.
f <- function(x){

sparseM and kronecker product_R latest version
Dear all,
I just installed the new version of R, 2.10.1, and I am currently
using the package sparseM. (I also use a 64 bit windows version)
I got a problem that I never had: when I try to multiply with a
kronecker product (%x%) two sparse matrixes I get the following
message:
Error in dim(x) <- length(x) : invalid first argument
I never had this problem with previous versions of R.
