similar to: Adding text comments to graphics device output files?

In R-devel (2015-08-12 r69024), capture.output() incorrectly duplicates the last line unless it ends with a newline. I don't see this in R 3.2.2 RC (2015-08-13 r69049). It seems to have started fairily recently; I spotted this yesterday after starting to get errors in my R.utils check that use capture.output(), cf.

Does it make sense to talk about the class of the output of substitute(...)? I'm puzzled by the following outputs: ee <- list( A = substitute( a <- 1 ), B = substitute({ a <- 1 }), C = substitute(( a <- 1 )), D = substitute( a == 1 ) ) > t(sapply(ee, FUN=function(e) { c(typeof=typeof(e), mode=mode(e), class=class(e)) })) typeof mode class A

In R, there's readline(), which is great because you can prompt the user, e.g. ans <- readline("Would you like to install Pandoc? [y/N]: ") without having to worry the message is intercepted by capture.output(), sink() or similar (which is used by dynamic report generators among other things). The message will always reach the user. (You can use sink(...,

Hi, is it possible to have non-Sweave vignettes(*) in inst/doc/ be listed under 'Downloads' on CRAN package pages? For instance, in my R.rsp package I have a inst/doc/report.pdf (part of the source *.tar.gz) that is not detected/listed. The PDF is not based on a Sweave vignette but an *.tex.rsp vignette that is dynamically created via inst/doc/Makefile. It is listed (*) BTW, can the

Hi. Q. Is there a way to record a plot using grDevices::recordPlot() without opening an interactive (=visible GUI window) graphics device (not even for a flash of a second)? Related: help("recordPlot", package="grDevices") says: "These functions record and replay the displaylist of the current graphics device." Is the intention that recordPlot() should be able to

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, I'm trying to figure out how to safely make sure that I close the same graphics device that I opened earlier in a thread (and not one opened by a parallel thread). In a *single-thread* environment, one can do the following to open and close a device: makePlot <- function(i) { filename <- sprintf("foo%d.png", i); png(filename); idx <- dev.cur();

Hi, I would like to know whether anybody knows a simple way to combine textual and graphical output in R. A typical analysis produces textual output (e.g. model fits) and plots in R. I would like to know whether R has the possibility of combining these into a single 'report' or output. An example of a program that does this is SPSS. After running the analysis you have a combination

Please don't do this to get the underlying vector length (or to achieve anything else). Setting/deleting attributes of an R object without checking the reference count violates R semantics, which in turn can have unpredictable results on R programs (essentially undebuggable segfaults now or more likely later when new optimizations or features are added to the language). Setting attributes

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

Calling library(..., quietly=TRUE) may still output: Loading required package: <other pkg> in some cases, e.g. > library("R.utils", quietly=TRUE) Loading required package: R.methodsS3 [...] I traced this to base:::.getRequiredPackages2(), which forgets to pass 'quietly' to an internal library() call: if (!attached) { if (!quietly)

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

In Section 'Indexing by vectors' of 'R Language Definition' (http://cran.r-project.org/doc/manuals/r-release/R-lang.html#Indexing-by-vectors) it says: "Integer. All elements of i must have the same sign. If they are positive, the elements of x with those index numbers are selected. If i contains negative elements, all elements except those indicated are selected. If i is

I'd like to follow up on this one. It may be that I have misunderstood something, but on both R devel (2012-02-22 r58452) and R 2.14.1 patched (2012-02-18 r58394) I can't seem to avoid loading ~/.Rprofile when I run 'R CMD <cmd>', e.g. R CMD build. For me, the loading of ~/.Rprofile by 'R CMD' started a few weeks ago, and I haven't seen it before. More details

Just thought I would mention that the issue below (and in https://stat.ethz.ch/pipermail/r-devel/2013-April/066318.html) is still not resolved. It hasn't been a big problem, but it potentially could be, if a critical package were to have this error on release day, then all its dependencies would fail to build, which would probably require us to postpone our release.

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
