Mossa, the issue you cite is lacking any pertinent information and it's not even clear why it should be an issue. The check is perfectly justified, it just reports whether a package using rust declares this correctly and where it downloads 3rd party content - something that is important to R us

Andres, correct me if I'm wrong, but the issue here is not initialisation but rather valgrind flagging. You simply have to call VALGRIND_MAKE_MEM_DEFINED() in your code after allocVector3() to declare that you have initialised the memory - or am I missing something? Cheers, Simon > On 30/

Re: [Rd] boneheaded BLAS questions

Ben, possibly useful project related to this https://github.com/staticfloat/libblastrampoline which is what Dirk referred to as the Julia state of art. It is actually much more complex than it sounds because of differences in naming and ABI between BLAS implementations, so simple switches don't

Re: [Rd] inheritance and attach

Terry, NEWS: CHANGES IN R 4.0.0 NEW FEATURES \item S3 method lookup now by default skips the elements of the search path between the global and base environments. If you use attach(), S3 methods are hence no longer dispatched to (because it is between global and base) unless you regi

Re: [Rd] An argument promise containing bytecode?

Taras, I don't think this has anything to do with promises, rather it is called Just-In-Time (JIT) compilation - see ?enablleJIT in R, it is enabled by default, so the function will be compiled on second use. Cheers, Simon > On Mar 7, 2021, at 11:12 PM, Taras Zakharko wrote: > > Dear all,

Re: [Rd] Apple M1 CRAN checks

Paul, this is being worked on. As you can imagine testing over 17,000 package in a M1 Mac mini isn't quite trivial. The first priority was to get the nightly R builds to work. Second was to get CRAN package builds to work. Third is to provide checks. The first two have finished last week and th

Re: [Rd] Checking multiple inheritance of S4 objects using R's C API

Emre, inherits() was designed for S3 classes and at C level only ever works for S3 classes. In S4 world you should use is(). There is no equivalent C-level API for is() so, unfortunately, you likely have to use Rf_eval() of is(x, "class"). At low-level there is R_S4_extends() which allows you

Re: [Rd] Request for a crop option on R's standard plot context menu

Toby, R provides more convenient ways for this - using window devices for any output other than screen is not its intended function. I would recommend using the off-screen devices devices such as pdf() or png() to generate output which also gives you far more control. Also please note that the

Re: [Rd] Unexpected behavior with inheritance and using S3 classes as slots in S4 class

Ezra, I think it's just the fact the you specified the wrong class inheritance in setOldClass() - it has to match you S3 definition, so it should be: setOldClass(c("b","a")) In which case it works: > n(s1 = b_1) An object of class "n" Slot "s1": [1] "world" attr(,"class") [1] "b" "a" Cheers,

Re: [Rd] New URL redirect checks

I can't comment for CRAN, but generally, shorteners are considered security risk so regardless of the 301 handling I think flagging those is a good idea. Also I think it is particularly bad to use them in manuals because it hides the target so the user has no idea what hey will get. Cheers, Sim

What do you mean by "manage unix signal"? The main signals like INT, PIPE or SEGV are handled by R and are not exposed to the user code. What exactly do you intend to do? Cheers, Simon > On Aug 14, 2020, at 6:44 PM, neonira Arinoem wrote: > > Hello > > Just wondering what is the best way to

Jeroen, This is great! It is definitely a good basis to build on. However, I wonder why your macOS setup is so extremely stripped down (not even Cairo, tcltk nor X11 - and not TeX, either) and as far from what we actually use as possible (using gcc instead of clang, openblas etc.). How do you

Mario, On unix if you use Rseve you can pre-load all packages in the server (via eval config directive or by running Rserve::run.Rserve() from a session that has everything loaded) and all client connections will have the packages already loaded and available* immediately. You could replace Rsc
