Hi Quite a few R packages are now available on GitHub long before they appear on CRAN, installation is simple thanks to devtools::install_github(). However, it seems to be common practice to keep the .Rd files (and NAMESPACE and the Collate section in the DESCRIPTION) in the Git tree, and to manually update it, even if they are autogenerated from the R code by roxygen2. This requires extra

Thanks for looking into it, your approach sounds good to me. See also R_has_methods_attached() (https://github.com/wch/r-source/blob/42ecf5f492a005f5398cbb4c9becd4aa5af9d05c/src/main/objects.c#L258-L265). I'm fine with Rscript not loading "methods", as long as everything works properly with "methods" loaded but not attached. -Kirill On 19.04.2016 04:10, Michael

See also .isMethodsDispatchOn, which is what trace uses to decide if the methods package needs to be loaded. ~G On Tue, Apr 19, 2016 at 5:34 AM, Michael Lawrence <lawrence.michael at gene.com > wrote: > Not sure why R_has_methods_attached() exists.

Does it make sense to be able to load an S4 object without the methods package being attached? I'm not sure implementation-wise how easy this would be, but it seems like any time there is an S4 object around, the methods package should be available to deal with it. ~G On Tue, Apr 19, 2016 at 7:34 AM, Michael Lawrence <lawrence.michael at gene.com > wrote: > Right,

Hi I've noted a minor inconsistency in the documentation: Current R-exts reads s = PROTECT_WITH_INDEX(eval(OS->R_fcall, OS->R_env), &ipx); but I believe it has to be PROTECT_WITH_INDEX(s = eval(OS->R_fcall, OS->R_env), &ipx); because PROTECT_WITH_INDEX() returns void. Best regards Kirill

Scenario: An S3 method is declared for an S4 base class but called for an instance of a derived class. Steps to reproduce: > Rscript -e "test <- function(x) UseMethod('test', x); test.Matrix <- function(x) 'Hi'; MatrixDispatchTest::test(Matrix::Matrix())" Error in UseMethod("test", x) : no applicable method for 'test' applied to an

Hi I haven't found a way to produce a tabulation from factor data with NA values using xtabs. Please find a minimal example below, it's also on R-pubs [1]. Tested with R 3.1.2 and R-devel r67720. It doesn't seem to be documented explicitly that it's not supported. From reading the code [2] it looks like the relevant call to table() doesn't set the "useNA"

Dear list For my work, it would be helpful if rpart worked seamlessly with an empty model: library(rpart); rpart(formula=y~0, data=data.frame(y=factor(1:10))) Currently, an unrelated error (originating from na.rpart) is thrown. At some point in the near future, I'd like to release a package to CRAN which uses rpart and relies on that functionality. I have prepared a patch (minor

Hi Accesses the $new method for a class defined in a package fails if the methods package is not loaded. I have created a test package with the following single code file: newTest <- function() { cl <- get("someClass") cl$new } someClass <- setRefClass("someClass") (This is similar to code actually used in the testthat package.) If methods is not loaded,

Hi Is there a way to detect that the process that corresponds to a pipe has ended? On my system (Ubuntu 13.04), I see > p <- pipe("true", "w"); Sys.sleep(1); system("ps -elf | grep true | grep -v grep"); isOpen(p) [1] TRUE The "true" process has long ended (as the filtered ps system call emits no output), still R believes that the pipe p is

Hi, After installing Rtools 3.1.0.1939 into c:\rtools31, when I call any (most?) of the commands in c:\rtools31\bin, I see strange messages printed to stderr. Example: C:\Rtools31>bin\tar 0 [main] tar 6084 shared_info::initialize: size of shared memory region changed from 27984 to 21136 bin/tar: You must specify one of the `-Acdtrux' options Try `bin/tar --help' or `bin/tar

Not sure why R_has_methods_attached() exists. Maybe Martin could shed some light on that. On Mon, Apr 18, 2016 at 11:50 PM, Kirill M?ller <kirill.mueller at ivt.baug.ethz.ch> wrote: > Thanks for looking into it, your approach sounds good to me. See also > R_has_methods_attached() >

Right, R_has_methods_attached() uses that. Probably not the right check, since it refers to S4 dispatch, while S4_extends() is used by S3 dispatch. Perhaps S4_extends() should force load the methods package? The above example works after fixing the check to ensure that R_MethodsNamespace is not R_GlobalEnv, but one could load a serialized S4 object and expect S3 dispatch to work with Rscript. On

This might be too big a change - but is it worth reconsidering the behaviour of Rscript? Maybe the simplest fix would be simply to always load the methods package. (I think historically it didn't because loading methods took a long time, but that is no longer true) Hadley On Tue, Apr 19, 2016 at 10:37 AM, Gabriel Becker <gmbecker at ucdavis.edu> wrote: > Does it make sense to be

Dear all, In my package I have a computational expensive Rnw file which can't pass R CMD check. Therefore I set eval=FALSE in the Rnw file. But I would like to have the pdf vignette generated by the Rnw file with eval=TRUE. It seems to me a static pdf vignette is an option. Any suggestions on this?
