Hi, I just tried to upgrade Nixpkgs to R 3.5.0, but unfortunately the new version fails its regression test suite. We configure the build using the flags "--without-recommended-packages", in case that's relevant. You can see a complete build log with all relevant information at [1]. Anyway, the test failures look like this: | make[3]: Entering directory

Hi, I have sparse (tridiagonal) matrices, and I use the Matrix package for handling them. For certain computations, I need to either set the first row to zero, or double the last row. I find that neither operation preserves sparsity, eg > m <- Diagonal(5) > m 5 x 5 diagonal matrix of class "ddiMatrix" [,1] [,2] [,3] [,4] [,5] [1,] 1 . . . . [2,] . 1

Friends I'm not seeing why the following occurs: > T1 <- (A1 - A2) %*% D > T2 <- (A1 %*% D) - (A2 %*% D) > identical(T1, T2) [1] FALSE Harold > dput(A1) new("dsCMatrix" , i = c(0L, 1L, 2L, 3L, 0L, 1L, 4L, 2L, 3L, 5L) , p = c(0L, 1L, 2L, 3L, 4L, 7L, 10L) , Dim = c(6L, 6L) , Dimnames = list(NULL, NULL) , x = c(5, 5, 5, 5, 5, 5, 10, 5, 5, 10)

Hi, we have installed R-2.8.1 using the current pgi compiler (8.0.2) for AMD64 on a SLES9 system. When I try to install "Matrix" everything is fine until the last step. make[1]: Leaving directory `/tmp/R.INSTALL.TW3399/Matrix/src/AMD' pgCC -L/usr/lib64 -L/usr/X11R6/lib64 -pgf90libs -o Matrix.so CHMfactor.o Csparse.o TMatrix_as.o Tsparse.o init.o Mutils.o chm_common.o

64-bit R-2.12.0 was installed on Sun SPARC Solaris 10. Compiler used is solstudio12.2. Attached is the configure script. I then tried to install a recommended package called Matrix. The compilation failed with the following messages, ....... CC -library=stlport4 -G -L/opt/csw/lib/sparcv9 -L/opt/solstudio12.2/prod/lib/v9 -o Matrix.so CHMfactor.o Csparse.o TMatrix_as.o Tsparse.o init.o Mutils.o

I need to perform a QR-decomposition of a sparse matrix, so I've been trying to use the Matrix package. Unfortunately I don't seem to be getting exactly the same results as if I had used the qr() command from the base package. Here is an example of what I'm doing. > spdata <-rpois(50,1) > y <- rnorm(10,0,1) > S <-

Dear Developers, motivated by the new Sun Studio checks I compiled R-devel and several of our packages with Sun Studio 12 on Fedora x64. Everything worked fine and R-devel runs, with the exception of package Matrix where compilation crashes with the following message. The error occurs during building of the recommended packages and also if Matrix is compiled separately: [...] CC -G -lCstd

Hi all, I have trouble to compile Matrix packages on Solar10 x86-64 with Sun compilers. I saw some postings on this but am not sure how to solve this problem. It is becoming critical as I cannot install biocLite() because of its dependency on Matrix. Could you direct me how to resolve the issue? Thanks in advance!

(Brief reply, I'm traveling but as per below, this is on my radar right now so wanted to comment.) Two points regarding "dotsMethods". 1. To clarify the limitation. It's not that all the arguments have to be of the same class, but there must be one class that they belong to or subclass. (So, as in the example in the documentation, the method could be defined for a class

Hello, I am using the Kinship package to draw a pedigree plot. I am trying to control the spacing between individuals in the pedigree. Currently, it is drawing a pedigree with too little space, so the text is overlapping. I'd like to increase the distance between individuals. According to the documentation, I would expect the following to be relevant:

Hi Im using the kinship package to draw a pedigree. On my data set this works fine but when i add indivudals to the pedigree i keep getting an error i hope someone can help me!

Dear R developers: I am a PHD candidate student in the school of public health of Peking University and my major is genetic epidemiology. I am learning the FAM-MDR algorithm, which is used to detect the gene-gene and gene-environment interactions in the data of pedigree.

Dear all, I'm trying to install lme4 (after having installed R 2.4.0 from source, and having installed the latest Matrix package). lme4 fails with the following message: pedigree.o definition of _lme4_xSym in section (__DATA,__common) pedigree.o definition of _lme4_ySym in section (__DATA,__common) make: *** [lme4.so] Error 1 ERROR: compilation failed for package 'lme4' ** Removing

In the 'doBy' package there is an esticon() function for calculating linear contrasts for various model types. I have defined an S3-method 'esticon.mer()' for 'mer' objects from the lme4 package.
