similar to: Using src/ to create executable - how to not build shared objects?

I was wondering if there's any non-executable stack patch for FreeBSD's kernel. I searched in google but all I got was some questions in freebsd-security back from 2001 and an answer saying someone heard about a project like this, but no information at all. Is there any patch like PaX or Openwall available for FreeBSD? I dont want to discuss if its useless or not since there're a

Hi, I'd like to spawn of a new R process from within R using system(), e.g. system("R -f myScript.R"). However, just specifying "R" as in that example is not guaranteed to work, because "R" may not be on the OS's search path. What is the best way, from within a running R, to infer the command (basename or full path) for launching R in way that it works on

I've rolled up R-1.6.1.tgz a short while ago. This is a minor upgrade, fixing an assortment of minor bugs, and one major one: 1.6.0 introduced a memory leak in deparsing, causing much trouble for people running simulations. You can get it from the developer site at http://cvs.r-project.org/pub/CRAN/src/base/R-1.6.1.tgz or wait for it to be mirrored at a CRAN site near you. Binaries for

Hi, I've just created: newEnvEval <- function(..., hash=FALSE, parent=parent.frame(), size=29L) { envir <- new.env(hash=hash, parent=parent, size=size); evalq(..., envir=envir); envir; } # newEnvEval() so that I can create an environment and assign objects to it in one go, e.g. env <- newEnvEval({ a <- 1; b <- 2; }); print(env$a); Does this already exists somewhere?

Also, as mentioned in my https://stat.ethz.ch/pipermail/r-devel/2012-August/064739.html, when not specifying the mode argument, the default on Windows is mode = "w" *except* for certain, case-sensitive, filename extensions: if(missing(mode) && length(grep("\\.(gz|bz2|xz|tgz|zip|rda|RData)$", url))) mode <- "wb" Just like the need for mode =

R Team, I was attempting to install Lindsey's rmutil.tgz and other non-CRAN packages using 'R INSTALL', for example 'R INSTALL rmutil.tgz' after downloading 'rmutil.tgz' from Lindsey's page (as linked from r-project.org page). Directly using the compressed file as 'R INSTALL rmutil.tgz' failed, though the shell help from 'R INSTALL --help'

Hi, str() on raster objects fails for certain dimensions. For example: > str(as.raster(0, nrow=1, ncol=100)) 'raster' chr [1, 1:100] "#000000" "#000000" "#000000" "#000000" ... > str(as.raster(0, nrow=1, ncol=101)) Error in `[.raster`(object, seq_len(max.len)) : subscript out of bounds This seems to do with how str() and

Hi, SETUP: Consider three packages PkgA, PkgB and PkgC. PkgA defines a generic function foo() and exports it; export(foo) PkgB imports PkgA::foo() and re-exports it; importFrom(PkgA, foo) export(foo) PkgC imports everything from PkgA and PkgB: imports(PkgA, PkgB) PROBLEM: Loading or attaching the namespace of PkgC will generate a warning: replacing previous import by

This may have been asked before, but is there an elegant way to check whether an variable/argument passed to a function is a "parse tree" for an (unevaluated) expression or not, *without* evaluating it if not? Currently, I do various rather ad hoc eval()+substitute() tricks for this that most likely only work under certain circumstances. Ideally, I'm looking for a isParseTree()

Aaaah ... and argh - I should have better not to post R question at midnight, especially when I know it forks the process and it's not using threads. Brain meltdown. (So, we'll proceed trying to use pthreads in matrixStats also for Windows). Sorry for the noise and thanks Kasper.

Hi, exists("foo", inherits=TRUE) check whether an object named "foo" exists, and get("foo", inherits=TRUE) retrieves it. I'm looking for a similar function to exists() that returns the environment where the object "foo" exists, iff at all. If not found, NULL is returned. Does that exist?

Dear List, I'd like to set up a package repository so I can use install.packages() on it for home-grown packages. I set up an AMPP infrastructure on a windows box already, but I'm pretty lost with respect to what to do next as I didn't do any web-programming/admin yet. Could anyone recommend some r-specific tutorials or has a couple of suggestions for me? I've had a look at the

On Windows there are a few 'pthreads' implementation, e.g. pthreads-w32 and winpthreads [https://cran.r-project.org/doc/manuals/r-devel/R-exts.html#Using-pthreads]. We're thinking of giving them a try for the matrixStats package, and basic tests indicates it works, but since Windows pthreads are not used by core R (or?) I've got a little bit worried that we will face overwhelming

Hi, I'm thankful for any help on installing RMySQL on Windows XP for R 1.9.1 The thread http://tolstoy.newcastle.edu.au/R/help/04/01/1021.html already tried to discuss the matter. It concludes that Windows Sources for Packages are alike the Linux ones. So I extracted the files from the RMySQL_*.tar.gz from http://stat.bell-labs.com/RS-DBI/download/index.html and stuffed them into a zip-file

Hi, I spotted what looks like another(*) mistake in 'R Language Definition' on how subsetting should work. In Section 'Indexing matrices and arrays' [http://cran.r-project.org/doc/manuals/r-release/R-lang.html#Indexing-matrices-and-arrays] one can read "Negative indices are not allowed in indexing matrices." but this is not true, e.g. > x <- matrix(1:12,

Is there a missing value constant defined for R_xlen_t, cf. NA_INTEGER (== R_NaInt == INT_MIN) for int(eger)? If not, is it correct to assume that missing values should be taken care/tested for before coercing from int or double? Thank you, Henrik
