...ing whether iswctype exists and is declared... no configure: error: Support for MBCS locales is required. ---- wctype.h appears to be usable when I declare export CC=gcc However, I encountered another problem during make. I think it is because I built the lapack libraries using intel compilers. sparseQR.o: In function `sparseQR_coef': sparseQR.c:(.text+0x52a): undefined reference to `Rf_protect' sparseQR.c:(.text+0x53a): undefined reference to `Rf_install' sparseQR.c:(.text+0x54f): undefined referenc...

...ant to calculate standardized residuals and need the diagonal elements of the hat matrix. I tried to adjust function hat() in the "stats" package for use with sparse matrices. But the method qr.qy does not seem to have a function available for the following signature: signature(qr = "sparseQR", y = "dgCMatrix") - although it indicates that it understands this signature. Following is a minimal example (in my application dd2 is too large for my memory): library(Matrix) data(KNex); mm <- KNex$mm mmQR <- qr(mm) dim(mmQR) # 1850 712 class(mmQR) # [1] "spars...

Hi, I came across a case when the dimensions of matrices returned by qr() operated on a sparse matrix does not coincide with the initial matrix. Here is a spinet code that should produce an example (one of many that I could provide): ?m=205 ?n=199 ?set.seed(7); ?a=matrix(rnorm(m*n), m, n) ?a[sample(seq(m*n), m*(n-4))]=0 ?a=as(a, "Matrix") ?qa=qr(a); ?stopifnot(nrow(qa at R) ==

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) str(trial <- data.frame(counts=c(18,17,15,20,10,20,25,13,12), outcome=gl(3,1,9,lab...

The bulk is on my forums - the final post for today is: Results to date: A. It looks like I am going to need a newer compiler for C - xlc/xlC V11 apparently does not understand this code: "/data/prj/cran/R-3.2.3/src/main/memory.c", line 2149.31: 1506-046 (S) Syntax error. I will have to check if R-devel has different code before asking for assistence. +2139 #ifdef
