Hi, When loading a package that provides the user-supplied RNG hook user_unif_rand, calling getNativeSymbolInfo("user_unif_rand") returns informations about the loaded symbol. I am using this to identify which package currently provides the RNG hook. The results are the same on windows and linux if only one library provides the hook. If one loads a second package that provides this

Hi R Developers, Greg is helping me with debugging R on Solaris 10 x64. Please let us know if you have any thoughts or tips that can help us debug this.

I use recordPlot() to save plots to disk that I render later to a variety of formats. This works fine for base R plots and ggplot2 plots, and also used to work for lattice plots. However somewhere in version 2.14 things stopped working for lattice plots. Here is an example: library(lattice); histogram(rnorm(100)); x <- recordPlot(); saveRDS(x, "myplot.rds"); y <-

In the following code routine 'initaquaphy' is defined in Fortran, and dynamically loaded into R.: test.f: subroutine initaquaphy(odeparms) external odeparms double precision pars(19) common /myparms/pars call odeparms(19, pars) return end $ R CMD SHLIB Aquaphy.f gfortran -fpic -g -O2 -c test.f -o test.o gcc -std=gnu99 -shared

I have a use case with tcltk-package where I need to repeatedly call Tcl/Tk functions very quickly. For such purpose, the standard R-interface turned out to be too slow, and better option has been to call package's C-function dotTcl directly from my own C-code. Before R 4.4.0 it was possible to use getNativeSymbolInfo("dotTcl","tcltk")$address (or

The R_registerRoutines C function allows the number of parameters to a .Call function to be registered. For example, the tools package function md5sum() calls "Rmd5", which has been registered to require just one parameter. But if it is called with the wrong number of parameters, only the first error gets caught: > library(tools) >

Hi R-devel, I'm trying to get R 3.2.1 working on Haiku (an open source OS inspired by BeOS, not Linux based) on i586. With a few small changes to library paths and ifdefs I am able to get a seemingly working R binary. The build process stops with the 'tools' package. The last lines from make are below. Does anyone have any tips? I'm rather new to debugging at this low level. Are

Hi all, Looking at the body for the function rnorm, I see that the body of the function is: .Call(C_rnorm, n, mean, sd) I want to implement functions that generate normal (and other) random variables. Now, I understand that I can perfectly well just call the R wrapper for these functions and that will be almost indistinguishable for most purposes, but for whatever reason I wanted to try and

Dear all, I am sending a patch for extending pdf device to embed popup text and web links. I implemented this feature by using annotation object, a interactive feature of pdf. You can see a sample code for using this feature in the following, and sample pdf is in

Hi, I am using premake4 generated make files to compile my projects, which works fine if I am using mingw32-make.exe from the MinGW 32 bit distribution, but doesn't work with the make.exe supplied by the latest RTools 2.16. That make.exe first complains it can't create directories and then that it has "no rule". So how comes there is no mingw32-make.exe along with RTools? I

Gabriel, Thanks for that! I guess I really should have figured that one out sooner, huh? I understand why that wouldn't be CRAN-compliant. But then, what *is* the proper way to do it? Is there any way I can call unexported functions from another package and have it accepted by CRAN? Also, if I instead re-write the random variable generating functions, do you have any idea of where the

Dear all, I’m not sure if it is O.K. to ask this question here. But where can I find the code for the function ‘C_Cdqrls’ which is called by the R function ‘lsfit‘. Thank you all. Sorry for being naïve if so. -------------------- Ziqiang Zhao 2013-04-23 [[alternative HTML version deleted]]

Robin Hankin's post reminded me to post about the following recent addition to 'Writing R Extensions', in the section on 'Submitting a package to CRAN' Ensure that the package sources are not unnecessarily large. ... As a general rule, doc directories should not exceed 5Mb, and where data directories need to be 10Mb or more, consideration should be given to a

I asked Tomas. Apparently this works: getNativeSymbolInfo("dotTcl",PACKAGE=getLoadedDLLs()$tcltk) and the tcltk behavior was changed by r84265 | hornik | 2023-04-15 08:44:36 +0200 (Sat, 15 Apr 2023) | 1 line Try forcing symbols in ff calls.

In versions of R prior to 3.0, by default .C and .Call would find the requested C function regardless of which shared library it was located in. You could use the PACKAGE argument to restrict the search to a specific library, but doing so was not necessary for it to work. R 3.0 introduced a significant change to that behavior; from the NEWS file: CHANGES IN R 3.0.0: PERFORMANCE

Well, For this particular use case why not just transform the parameters at the R level and then call the existing function?

Hi, I'm trying to use a list of symbols as one of the values to be substituted in a substitute expression, but I can't figure out how to write the correct expression for my problem. Let me illustrate a simple example of what I'm trying to do. The following code snippet will evaluate to '5': symname <- 'foo' foo <- 5 expr <- substitute(c(expr), list(expr =
