Not sure why R_has_methods_attached() exists. Maybe Martin could shed some light on that.

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

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"

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

...s() should probably throw an error when the methods namespace is not loaded. And the check should be changed to directly check whether R_MethodsNamespace has been set to something other than the default (R_GlobalEnv). Agreed?

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

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

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?

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,
