I am moving my first steps in writing and compiling C code and calling it from R. (I am also new to shared libraries...) My problem is that my C code uses a C function contained in another library (".a", not ".so" - is that the problem?). This is how I compile the file with the functions I want to call from R: cd /export/home/gpetris/ R SHLIB tryit.c cc

Dear all, I am trying (without much success) to use the fuction 'silhouette'. Would anyone encountered that before (or would know where I am wrong ?) Please find below the R ouput. Thanks in advance, L. > s <- silhouette(ct, as.dist(metric)) Error in "[<-"(*tmp*, iC, "sil_width", value = s.i) : number of items to replace is not a multiple of replacement

Hello all, This might have been fixed in later versions (I am using R1.7.0), r-help archive contains messages reporting similar problems but no reports of codes fixes. I have encountered a couple of problems using the silhouette function. one occurs when the clustering contains clusters composed of 1 element (Martin Maechler posted code few months ago that fixes a similar problem that occurs

Hello, I am new to R on Linux (and to LINUX), running a 1.9.1 on a Linux MDK10.0. When updating or installing different packages, I get messages like this (under), the package doesn't install. Can anyone help me? I know this is all to little information, but I don't know were to start. I think there is something wrong in how or were the C++ or fortran compilator is installed?? Thanks, Geir

Hi, I have a S3 package with namespace called "myS3Pkg". Inside my package I would like to create a S4 class which extends (adds 2 slots) another S4 class from some other package. The class should be created in "myPkg" environment (and not global environment). Using: setClass("myS4class", representation("otherS4class", mydata = "numeric"),

This is a Request For Comment, also BCCed to 390 package maintainers of reverse dependencies of the Matrix package. Most users and package authors working with our 'Matrix' package will be using it for numerical computations, and so will be using "dMatrix" (d : double precision) matrix objects M, and indirectly, e.g., for M >= c will also use "lMatrix" (l:

Hello. This question concerns the Methods package. I have created a new class and am trying to set a method for it for S4 group generic "Summary". I have run into some signature problems. An example: > setClass("track", representation(x="numeric", y="character")) [1] "track" > setGeneric("max", group="Summary")

Using the Matrix package, how can I create a row-oriented sparse Matrix from scratch populated with some data? By default a column-oriented one is created and I'm aware of the note that the package is optimized for column-oriented ones, but I'm only interested in using it for holding my sparse row-oriented data and doing basic subsetting by rows (even using drop=FALSE). Here is what I

Dear all, I need to re-define some mathematical operators (+, *, /, etc) for an S4 class based on array. All references I have found (S Programming, Green Book) show how to define S3 methods for this (like in page 89 of S Programming for "-.polynomial"). What is the preferred S4 way for doing this? I hope I haven't missed some obvious piece of documentation. Many thanks, Iago

After loading the package "Matrix" (version 0.995-12), using the summary function with an lme (package nlme version 3.1-75) object results in an error message saying Fehler in dim(x) : kein Slot des Namens "Dim" f?r dieses Objekt der Klasse "correlation" (translated: 'Error in dim(x) : no slot of the name "Dim" for this object of class

It seems that it is possible to pass a matrix to C++ by using .C() The R part of the interface should be something like: ('C++function', matrix, numberRows, numberColumns ) ...I guess. The C++ part of the interface could be something like void C++( double matrix[][], int numberRows, numberColumns ) but C++ requires to indicate the number of columns, that is, instead of matrix[][], it

Hi Martin I got stung by this last week. glmnet produces a coefficient matrix of class ?dgCMatrix? If a predictor matrix was created using sparseMatrix as follows, one gets unexpected results, as this simple example shows. My fix was easy (I always convert the predictor matrix to class ?dgCMatrix? now) Trevor > y=Matrix(diag(4)) > y 4 x 4 diagonal matrix of class "ddiMatrix"

Hi Martin, package arules heavily relies on ngCMatrix and uses multiplication and addition for logical operations. I think it makes sense that in a mixed operation with one dgCMatrix and one ngCMatrix the ngCMatrix should be "promoted" to a dgCMatrix. The current behavior of %*% and friends is in deed confusing: > m <- matrix(sample(c(0,1), 5*5, replace=TRUE), nrow=5) >

I thought I'd give this another shot before the official release. I tried building R-beta_2004-04-07 on the AIX system that I have access to, and it seemed to failed at lazy-loading survival. I'd very much appreciate any pointer on what to try or look for next. 1. I set OBJECT_MODE to 64 for building 64-bit binary. 2. I edited config.site with the following: CC="xlc_r"

Hi, I would like to connect my GHA-system to R and to deliver the library to users of R. could you give me a comprehensive example containing the step by step procedure to: 1. create a callable library with R binaries (not having a standalone version of R with its own main()). If possible, I would like to run the system on unix,alpha,linux computers as well as on IBM's parallel

Hi, I have sent this message before does any one have any ideas? We really need to be able to run Java class files from the root of a samba share. I think that the problem may have to do with Samba file name mangeling and that this may be preventing the java virtual machine from finding the calls file through the classpath environment variable. Here is the original message. Can any one help? We
