Some already know, but I think it deserves a bit of a attention here as well: It looks like we're about to get new features in R that will be very powerful! That should be a good enough teaser...

Hi, for simply for troubleshooting purposes (e.g. making sure that --max-ppsize=N) is set, is there a way to query the pointer protection stack size from R? I tried to grep the source code and couldn't find...

Hi, I found in a bit of code the following test for infinity: if (x == Inf) ... Is that valid, or should it be (as I always thought): if (is.infinite(x)) ...? Does it depend on whether 'x' is float or...

Hi, is it possible to add a custom script such that it is called via R CMD <custom>? Is R CMD searching for it elsewhere than R_HOME/bin/? I'm looking for an non-admin alternative, so copying the...

Only for the record, an unnecessary overhead when nothing is assigned: > x <- integer(10) > str(x) int [1:10] 0 0 0 0 0 0 0 0 0 0 > x[c()] <- 1.0; > str(x) num [1:10] 0 0...

Hi, FYI, the devel version of EBImage won't build due to a "typo" in DESCRIPTION: http://bioconductor.org/checkResults/2.3/bioc-LATEST/EBImage/gewurz-buildsrc.html I've contacted the new maintainer (Wolfgang Huber), but he's won...

For a couple of days, MacOS X binaries are not build on CRAN (for my recently uploaded packages only?): The R.oo package is listed as "MacOS X binary: not available, see check log?", but the 'check log' show no...

It appears that http://r.research.att.com/, which provides "daily builds of the R GUI, R-patched and R-devel" for OSX, is down (at least since yesterday). I didn't find any contact information in online web caches...

In case it's not known, paraphrasing from CRAN notification email, CRAN [sic!] packages: TROM, demi, diffMeanVar, maGUI, metaboGSE risk being archived on December 7 because broken Bioconductor dependencies: Heatplus, missMethyl, oligo, oligoClasses, topGO prevent pdInfoBuilder from being installed. I...

FYI, http://cran.r-project.org/src/base/NEWS.html [May 18, 2011] is for R v2.13.0 whereas http://cran.r-project.org/src/base/NEWS [July 8, 2011] is for R v2.13.1. The former is...

Hi Oleg, as I already told you but cannot be said too many times, your EBImage package is/will be one of major contributions to R this year. I noticed that both: http://www.ebi.ac.uk/~osklyar/projects/EBImage...

Is there a low-level function that returns the length of an object 'x' - the length that for instance .subset(x) and .subset2(x) see? An obvious candidate would be to use: .length <- function(x) length(unclass(x)) However, I...

Nothing serious, but I just noticed that if you pass a function as the 'length' argument of vector(), you get the following misinformative error message: > vector("list", length=function() {}) Error in vector("list", length = function() { : negative length vectors are not...

Hi, is there a hasNA() / an anyNA() function in R? Of course, hasNA <- function(x) { any(is.na(x)); } would do, but that would scan all elements in 'x' and then do the test. I'm looking for a more...

FYI, I found the following to give a useful introduction to what copyright/left is, the ideas behind open-source licenses, and more: Fontana R. et al. 2008. A Legal Issues Primer for Open Source and Free Software Projects. Version...

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 base R, there are lots of environment variables with either prefix 'R_' or '_R_', e.g. R_ENABLE_JIT and _R_RNG_VERSION_. I always considered R_* variables to be "public" and _R_*_ ones being "internal" but realized I...

Hi. Is there a way, without using R, to query bioconductor.org (or any other reliable/maintained resources) for what the current release version of Bioconductor is? Something like: $ curl https://bioconductor.org/api/version 3.6 or possibly something...

Hi, without arguing for doing it or not, is the following a correct way to reorder the search path: moveInSearchPath <- function(from, to) { # Excluding validation of 'from' and 'to' here etc. # Get enviroment to be moved env <- pos.to.env...
