similar to: Support for signing R packages with GPG

Thanks Jeroen. The R Foundation has recently formed a working group to look into package authentication. There are basically two models. One is the GPG based model you describe; the other is to use X.509 as implemented in the PKI package. It's not yet clear which way to go but we are thinking about it.

The package I'm working on can extract data from external packages but would otherwise have no dependency on them. However, I desire to be able to dispatch based on an external S3 class if its package is attached (.First.lib). My code is S4-based and its package has NAMESPACE. Registering the external class prior to the other package being attached doesn't seem to work so I am attempting

When using multicore-forking of the parallel package, is it possible for a child process to know that it is a fork? Something like: parallel::mclapply(1:10, FUN = function(i) { test_if_running_in_a_fork() }) I'm looking into ways to protect against further parallel processes (including threads), which not necessarily are created via the parallel:mc* API, are being spawned off recursively.

Hi, I'm hoping to get some clarification of the intent of some of directives used in NAMESPACE files. 1. Is import(somePkg) also intended to import all classes and methods that are exported via exportClasses and exportMethods in somePkg? I think import pulls in classes and methods, but it isn't clear from the docs whether this is as intended. 2. What is exportMethods intended

I would like to propose that Rf_mkString(NULL) and Rf_mkChar(NULL) return NA rather than segfault. Case: the mkString() and mkChar() functions are convenient to wrap strings returned by e.g. external C libraries into an R vector. However sometimes a library returns NULL instead of a string when the result is unavailable. In some C libraries this can happen unexpectedly or is even undocumented. A

A new version of the ggplot2 web application is available at http://www.yeroon.net/ggplot2. New features include 1D geom?s (histogram,?density, freqpoly), syntax mode (by clicking the tiny arrow at the?bottom), and some additional facet options. Furthermore some minor?improvements and fixes, most notably for Internet Explorer. As usual, a little demo video that shows how to use the new features:

Dear R Developers, I started programming in R just last January, for which I read (, summarized and memorized) 2 incredible R Programming books: "R Cookbook" and "R Graphics Cookbook". However, I did before know how to program in MariaDB SQL language, and had submitted for their bug platform previously some bugs (https://jira.mariadb.org/projects/MDEV/issues), which is based

I think that this is because `[<-` dispatches on S4 methods only if the first argument is S4. ?"[<-" says: "These operators are also implicit S4 generics, but as primitives, S4 methods will be dispatched only on S4 objects ?x?."

I would like to print some tables and figures to a PDF device on a CentOS 5 vps. However, I cannot seem to get the latex function from Hmisc working. I followed the example, and got an error: sh: xdvi: command not found. I tried installing the 'tetex-xdvi' linux package, and now it returns: Error: Can't open display. I guess the reason for this is that the machine is a VPS terminal, so

I am using numerical optimization to fit a 1 parameter model, in which the input parameter is bounded. I am currently using optimize(), however, the problem turns out to have local minima, and optimize does not always seem to find the global minimum. I could to write a wrapping function that tries multiple intervals or starting values, but I would prefer a package that has built-in methods to make

Is there a way to get the status code of a pipe() command? The documentation suggests that it might be returned by close, however this does not seem to be the case. con <- pipe("cat /etc/passwd", "r") stream <- readLines(con, n = 10) err <- close(con) print(err)

I am looking for a function to flatten a list to a list of only 1 level deep. Very similar to unlist, however I don't want to turn it into a vector because then everything will be casted to character vectors: x <- list(name="Jeroen", age=27, married=FALSE, home=list(country="Netherlands", city="Utrecht")) unlist(x) This function sort of does it: flatlist

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 <-

We recently started noticing freezes that appear only on 32bit systems (both linux and windows) with a relatively recent versions of R 3.2.0, including the RC. It looks like the problem can be traced back to the use of R_ObjectTables (see R_ext/Callbacks.h) The problem is a bit difficult to reproduce because it does not appear on x64 and because the official R interface to this functionality, the

Hi all, I am testing R 4.0 and ran into an issue with timezones on Ubuntu Focal: converting a timestamp to another timezone results in NA: as.POSIXct(as.POSIXlt(Sys.time(), tz = "CET"), tz = "EST") This only happens on Ubuntu Focal, it seems to work fine on Ubuntu Bionic. I am the standard ubuntu docker image icw/ r-base from Dirk's ppa:edd/r-4.0 on both systems. Am I

Dear list, I'm using R in a corporate environment and was interested how R checks integrity of packages during an installation. I saw (and verified my suspicion in the code[1]) that the verification purely relies on MD5. >From an IT security perspective, this can be improved. My question is: Is is possible to force R to verify integrity via SHA256 or even OpenPGP signatures? If not are
