Hello, Consider this function for generalized ridge regression: gre <- function (X,y,D){ n <- dim(X)[1] p <- dim(X)[2] intercept <- rep(1, n) X <- cbind(intercept, X) X2D <- crossprod(X,X)+ D Xy <- crossprod(X,y) bth <- qr.solve(X2D, Xy) } # suppose X is an (nxp) design matrix and y is an (nx1) response vector p <- dim(x)[2] D<- diag(rep(1.5,p)) bt

Hi all, I need some solution in the following problem. The following error appears when i use "mgcv" package for implementing GAM.

Dear all, I was wondering if there is a way to explore a syntax of particular function without package installation? I am trying to write my own functions, and I would like to see how other people approached similar problems. If every time I have to install/load package to be able to explore function syntax I end up installing loads of packages I am never going to use. I have also tried

for the moment, I'm using: .onAttach <- function(libname, pkgname) { .bbg.db.conn <<- dbConnect(dbDriver("PostgreSQL"), user="blah","blah") } .onUnload <- function(libpath) { dbDisconnect(.bbg.db.conn) } which results in a hidden global variable in the global environment. I would prefer to make the assignment only in the package namespace.

Dear useRs, Is it possible to get the R package usage statistics? That is, does R contain any tools to estimate which packages were used and how often? I am going to temporary change the workplace and packing the data and their processing scripts on my computer in order to continue my projects. During my work on the current workplace I periodically have had installed new R

Hi, I have seen the answer to this sometime before but I just can't find it again - pointers appreciated. I have a package that contains some data.frames saved as .Rda files in the data/ directory. When the package is loaded I would like to have them be available in the workspace (without the user having to explicitly load them using data(...)). If my package does not use a NAMESPACE, I can

Dear All I am having problems to install the package COZIGAM. Despite I have the update version of R (3.0.2) when I try to load the package I cannot find it in the list of available packages. If I try to install it from a local zip file I do get this error message: Error in read.dcf(file.path(pkgname, "DESCRIPTION"), c("Package", "Type")) : cannot open the

Was looking at what was output for <pkgname>-package.Rd and wondered if any there was any means (via macro, etc) to merge some of the same information with a template for my package manpage? As much (all?) of the generated information was already provided in the DESCRIPTION, I'd prefer not to have to update the information in multiple places. I'm thinking here that I could provide a

Hi all, I'm very new to R. I have installed R 1.9.0 on Linux (Fedora). Now I got an self-made package comprising R functions as well as C-Code which are used in several R functions. I installed the package without any error (see install log below). Then, I checked in /usr/lib/R/library if the package izbi exists and it exists. But whenever I try to load the library on the command line I

Hi, I'm developing a package whose API is only meant to be used in other packages via imports or pkg::foo(). There should be no need to attach this package so that its API appears on the search() path. As a maintainer, I want to avoid having it appear in search() conflicts by mistake. This means that, for instance, other packages should declare this package under 'Imports' or

Hi, I apologize for this often/old question. I found some hints but couldn't solve the problem so far. I have C functions (incl. the header files) as well as the R wrapper functions which I want to use for faster calculations. These functions are included in a R package. The installation process seems to be ok (no errors). I also can load the package without errors. But when I call the

Hey everyone, I have made a package and wish to release it but before then I have a problem. I have a few functions in this package written in R that I wish to hide such that after installation, someone can use say the function >foo(parameters = "") but cannot do >foo. Typing foo should not show the source code or at least not all of it. Is there a way to do this ? I have searched

Hi all, I ran into a strange error: I am trying to create a package skeleton for a new source package from within a function. Objects that are created in this function are to be included in my package, but for some reason, I get an error message saying that these objects cannot be found. Here is the code: ###### myfun <- function(pkgName,x){ myenv <- new.env() apply(x, 1,

Is it possible to install a solaris streams package with puppet? As some of my machines are not allowed to be a nfs client, I transfer the bunch of packages to these clients with the file type and puppet:// ... If the packages are in filesystem format there can be hundreds of files within large packages. It takes a huge amount of time to transfer all of them. So I''ve changed them into

Hi, I am having a problem building binary packages for Windows recently. Normally, I use the "Murdoch-Sutherland" tool set, http://www.murdoch-sutherland.com/Rtools/ just build source packages by R CMD build <pkgname> and install these with R CMD INSTALL <pkgname> But now, for someone without having this tool set installed, under Win XP, with R-2.10dev

I am trying to get a function written in R that calls a cascade of functions from the graphics package, and I want to eventually call replacements to functions in the graphics package instead of the originals. Specifically, I have a function that calls qqnorm in stats, which calls qqnorm.default in stats, which calls plot in graphics, which calls plot.default and plot.new, and I want my own

Dear r-help group, I am creating a package that has some FORTRAN code under windows. I have read through "Writing R Extension" but still not so clear about the steps. Before R CMD build, how can I create a dynamic library and later in my R function using dyn.load ("xxx.dll") ? If I already have a .dll file, can I build the package with the dll file directly ? Does any one
