Hello, I would like to read and write sparse matrices using the functions write.matrix.csr() and read.matrix.csr() of the package e1071. Writing is OK but reading back the matrix fails: x <- rnorm(100) m <- matrix(x, 10) m[m < 0.5] <- 0 m.csr <- as.matrix.csr(m) write.matrix.csr(m, "sparse.dat") read.matrix("sparse.dat") Error in initialize(val...

I would like to add a class to the SparseM package. I have a class "matrix.csr" that describes a matrix in compressed sparse row format, now I would like a class matrix.diag.csr that describes such objects when they happen to be diagonal. The idea is that matrix.diag.csr objects should behave (later in life) exactly like matrix.csr objects, the distinction is only needed...

I'm trying to resolve a small problem that has arisen from introducing a NAMESPACE for the package SparseM. Prior to the namespace I had a class "matrix.diag.csr" that consisted of diagonal sparse matrices. It was defined to have the same attributes as the matrix.csr class and setAs was used to define how to coerce integers and vectors into this form: setClass("matrix.diag.csr","matrix.csr") setAs("numeric","matr...

...rday I posted a patch request to the llvm-commits list requesting that someone could apply a patch to Triple.h and Triple.cpp for me. I didn't get any response so I wondered whether I should have posted to this list instead. My story is as follows: we are trying to get lldb/llvm support for CSRs range of Kalimba DSPs. Eventually we are planning to hire someone to write an LLVM backend for the core, but currently we/I are making to do with porting lldb to debug Kalimba chips via a bespoke gdbserver implementation. In order to get lldb to recognise Kalimba DSPs I have had to add defin...

Hi, I am new to R. I don't have strong background of statistics. I am a student of Geotechnical Engineering. I tried to run a nonlinear regression for a three-variable function, that is N = f(CSR, ev) # N is a function of CSR and ev, and N = CSR/(A +B*CSR), wherer (A,B) are function of ev. N, CSR and ev are observed in the experiments. Following is my R script. rm(list=ls()) library(nlme) # assign data N <- c (30.03,16.62,10.88,36.47,20.24,38.17,36.47,34.80,19.00,32.37,14.40,35.63...

When compiling C code below for AArach64, I saw that shrink-wrapping didn't happen due to the very early uses of CSRs in the entry block. So CSR spills/reloads are executed even when the early exit block is taken. int getI(int i); int foo(int *P, int i) { if (i>0) return P[i]; i = getI(i); return P[i]; } It's not that hard to find such cases where RegAllocGreedy aggressive...

In the last few days I've received couple of messages pointing out that our SparseM package fails to install on the patched version of 1.7.0. Laurent Gaultier kindly suggested that replacing: setGeneric("as.matrix.csr") by setGeneric("as.matrix.csr", function(x, nrow, ncol, eps) standardGeneric("as.matrix.csr")) was sufficient to fix the problem. Unfortunately, the story is a bit more complicated than that. After this substitution and some similar ones for a few other setGeneric() c...

I looked on the openssl man page but am too dense with commands to understand what I need to do..... Ran into problems generating a key and CSR for SSL, because the web site is on a server with an old Ensim Control Panel. Please someone knowledgeable, give me the openssl commands I need to use, after I ssh into the web site, to generate a 2048 bit key and csr. TIA and Happy New Year!

Hello, The write.matrix.csr() function of the e1071 package contains a bug. Try the following: library(e1071) m <- 1 - diag(10) sm <- as.matrix.csr(m) write.matrix.csr(sm) The resulting file (out.dat) contains only the two lines below: 2:1 3:1 4:1 5:1 6:1 7:1 8:1 9:1 10:1 1:1 3:1 4:1 5:1 6:1 7:1 8:1 9:1 10:1...
