similar to: S3 dispatch for S4 subclasses only works if variable "extends" is accessible from global environment

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,

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

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() >

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

Right, the methods package is not attached by default when running R with Rscript. We should probably remove that special case, as it mostly just leads to confusion, but that won't happen immediately. For now, the S4_extends() 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

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"

Even though I use aseert np.all(m1 == m2) when working with NumPy, I got accustomed to the "handy shortcut" that I can omit all() with R vectors and matrices.

I have encountered a need for float-to-int casts that saturate to min/max when the value is out of the range of the target type. It seems that there is no intrinsic to do this, currently, but on IRC it was pointed out that a patch [1] has been proposed to implement this functionality in exactly the way that I was looking for. It looks like the discussion has died out but I was hoping maybe to

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 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,
