Two of them I can fix and a patch is supplied below. I hope this is useful for the current source (if these haven't been fixed already :) 1) cov cov() fails when it's argument is a matrix with one column and with column names

Salut alex, j''ai un petit souci. quand j''utilise "demotaskbaricon" avec traducteur-wxruby, que j''ouvre mon application(donc l''icone apparaît dans la barre de lancement rapide) et que je ferme mon application, l''icone disparaît tout de suite. Mais quand je l''utilise avec l''exemple Wizard et que je ferme mon application

I added "plogis" to the derivative table in the development version of R; the patch against yesterday's R-devel src/deriv/main.c is available at http://www.zoology.ufl.edu/bolker/deriv_patch.txt .

R community, As you may know, R's iconv doesn't work well converting to and from encodings that allow embedded nulls. For example > iconv("foo", to="UTF-16") Error in iconv("foo", to = "UTF-16") : embedded nul in string: '\xff\xfef\0o\0o\0' However, I don't believe embedded nulls are at issue here, but rather that R's iconv

Hi All, I am trying to write a source-to-source compiler for R. I am trying to leverage the R parser code for the purpose. I am trying to transform the SEXP returned from the parser into an AST for our own Ruby embedded Domain specific language. I tried using R CMD SHBIN to compile a C function that parses arbitrary R expressions. But I think, the generated .so file can be used from within R and

Hi, I've read ?is.unsorted and searched. Have found a few items but nothing close, yet. Is the following expected? > is.unsorted(data.frame(1:2)) [1] FALSE > is.unsorted(data.frame(2:1)) [1] FALSE > is.unsorted(data.frame(1:2,3:4)) [1] TRUE > is.unsorted(data.frame(2:1,4:3)) [1] TRUE IIUC, is.unsorted is intended for atomic vectors only (description of x in ?is.unsorted). Indeed

Summary: patch to add environment parameter to load() to allow -------- specification of destination environment. --> Patch against R 0.63.2 appended at end of this message. <-- Story: ------ I've been running some rather long MCMC chains, which occasionally crash, either due to an "Invalid tag in name extraction" error, or due to the machine going down. (I'm playing

Inside of the anyNA() function, it will use the legacy any(is.na()) code if x is an OBJECT(). If x is a vector of POSIXct, it will be an OBJECT(), but it is also TYPEOF(x) == REALSXP. Therefore, it will skip the faster ITERATE_BY_REGION, which is typically 5x faster in my testing. Is the OBJECT() condition really necessary, or could it be moved after the switch() for the individual TYPEOF(x)

Hi, I have spotted a minor bug in do_strptime() function.

I would like to see how the matrix multiplication operator %*% is implemented (because I want to see which external Fortran/C routines are used). How can I do so? Best S??ren

It's tough to reliably reproduce, but I often get stack imbalance warnings when calling max.col() on non-real/double matrix. The code is conditionally PROTECTing but not incrementing its nprot counter for the eventual UNPROTECT. Pretty sure this would fix (but I haven't tested it): Index: array.c =================================================================== --- array.c (revision

I'm trying to figure this out with "Writing R Extensions" but there's not a lot of detail on this issue. I want to write a (very simple really) C external that will be able to take "..." as an argument. (It's for optimizing a function that may have several parameters besides the ones being optimized.) I got the "showArgs" code (from R-exts) to compile and

R version 1.0.1 OS RedHat Linux 6.1 In attempting to test for numeric vectors in a data frame, I tried: apply(dataframe,2,is.numeric) and found that it returned FALSE for all vectors whether they were numeric or not. I tracked this to the fact that as.array() was converting the data frame to character vectors, and thought I could solve it by using array(), which preserved the mode of the

I'd like to propose a change to the R language so that calling 'parent.env<-' on a package namespace or package imports is a runtime error. Currently the documentation warns that it's dangerous behaviour and might go away: The replacement function ?parent.env<-? is extremely dangerous as it can be used to destructively change environments in ways that violate

> I would argue that you should build the RC and the release the same way. I've had to fix bugs were someone had an assert with a side-effect, and the code with asserts turned off didn't work. OK, so it's clearly important to provide and test against RC's in the actual release configuration, especially since assertions can introduce bugs on their own. Arguably however

Can we use the "bytes" encoding for such environment variables invalid in the current locale?
