[Rd] The finalizer of the externalPtr does not work when closing R?

Hi all, I found that the finalizer of the externalPtr is not called when R is quitting. However, manually calling GC() works fine. This behavior is observed on devel R 2020-04-02 r78142 on Win and R 3.6.3 on Ubuntu. I make a reproducible package here: https://github.com/Jiefei-Wang/example Here

[Rd] Inconsistant result for normalizePath on Windows

Hi all, I saw a quite surprising result in the devel R when using the function *normalizePath*. If the input is a path to a folder, the function returns an absolute path with/without a slash at the end depending on the existence of the folder. I know both results are valid on Windows but this beha

[Rd] R CMD INSTALL cannot recognize full path on Windows

Hi all, Here is a bug(or feature?) that exists at least from R 2020-02-24 r77852 to 2020-03-09 r77919 on Window. Consider this example makefile in a package ``` *test1=$(shell echo 'runif(3)'|R --vanilla --slave)test2=$(shell echo 'runif(3)'|"C:/Program Files/R/R-devel/bin/R" --vanilla --sla

Good question, I cannot speak for R's developers but I would like to provide some information on the problem. Here are the first few lines of the dnorm function located at src\nmath\dnorm.c: ``` double dnorm4(double x, double mu, double sigma, int give_log) { #ifdef IEEE_754 if (ISNAN(x) || IS

Hi Morgan, My solutions might not be the best one(I believe it's not), but it should work for your question. 1. Have you considered Rf_duplicate function? If you want to change the value of `a` and reset it later, you have to have a duplication somewhere for resetting it. Instead of changing the

[Rd] Unexpected behavior when using macro to loop over vector

Hi all, I found an unexpected behavior when I was trying to use the macro defined in "R_ext/Itermacros.h" to loop over an atomic vector. Here is a minimum example: C++ code ``` #include "R_ext/Itermacros.h" #define GET_REGION_BUFSIZE 2 //Redefine the macro since C++ is not happy with the implici

Re: [Rd] S4SXP type vs S4 object bit?

Hi Travers, Just an additional remarks to Michael's answer, if your S4 class inherits from R's basic types, say integer, the resulting object will be an INTSXP. If your S4 class does not inherit from any class, it will be an S4SXP. You can think about this question from the object-oriented framewo

[Rd] [ALTREP] What is the meaning of the return value of Is_sorted and No_NA function?

Hi, I would like to figure out the meaning of the return value of these two functions. Here are the default definitions I find from R source code: static int altreal_Is_sorted_default(SEXP x) { return UNKNOWN_SORTEDNESS; } static int altreal_No_NA_default(SEXP x) { return 0; } I guess the m

[Rd] What is the best way to loop over an ALTREP vector?

Hi devel team, I'm working on C/C++ level ALTREP compatibility for a package. The package previously used pointers to access the data of a SEXP, so it would not work for some ALTREP objects which do not have a pointer. I plan to rewrite the code and use functions like get_elt, get_region, and get_

[Rd] Questions regarding ALTREP_SET_ELT APIs

Hi all, I'm wondering if there is any way to define a `SET_ELT` function for an ALTREP class? I see there are ` ALTINTEGER_SET_ELT` etc. functions exported in Rinternal.h, but there is no corresponding ALTREP APIs to define them. The only way to set the value of an ALTREP is through a pointer, whi
