Hi Alexandre, I'm not an R expert so this is only my personal thought: I don't think you can achieve what you want exactly. A possible solution would be defining a binary operator %*%, where you can replace the asterisk with any function name you want. The function %*% is special since it has two arguments, left operand and right operand respectively. You then can call the `substitute`

...x) : 0; } If the argument x is not an ALTREP, the function will return 0, and a default method will be used, so there is no way to return true without loop over the argument x right now. I hope this could be changed in the future.

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 framework: If one class inherits the integer class, what should R do to make all the integer related

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) || ISNAN(mu) || ISNAN(sigma)) return x + mu + sigma; #endif if(!R_FINITE(sigma)) return R_D__0;

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 --slave)test3=$(shell echo

Hi all, I used `gzfile` and `gzcon` to read a compressed file but I found that `gzcon` gave me a different result than `gzfile`. It seems like the `gzcon` does not handle the data correctly. I have posted an example below. In the example, a portion of a compressed file is downloaded from Google Cloud as a raw vector, and the data is saved into a temp file. If I use ` gzfile` to read the file, it

Hi I found a weird problem in testthat while working with an ALTREP package. The package name is AltWrapper. My ALTREP serialize function is called even when I'm trying to serialize a non-ALTREP object. Here is an example ``` context("altrep") length_func<-function(x){ return(length(x)) } setAltClass(className = "test", classType = "real")

Hi all, I would like to determine if an ALTREP object is from my package, I see there is a function `ALTREP_CLASS` defined in RInternal.h but its return value is neither a `R_altrep_class_t` object nor an STRSXP representing a class name. I do not know how to correctly use it. Any suggestions? Thanks, Jiefei [[alternative HTML version deleted]]

Thank you, Tomas. I appreciate your help. BTW, could you also add an explicit type conversion in " ITERATE_BY_REGION_PARTIAL" macro while you are fixing the bug? C++ compiler does not happy with the implicit conversion from void* to T* somehow and I have to redefine it before using the macro.

Hi, I am curious about whether there exist thread-safe functions in `Rinternals.h`. I know that R is single-threaded designed, but for the simple and straightforward functions like `DATAPTR` and `INTEGER_GET_REGION`, are these functions safe to call in a multi-thread environment? Best, Jiefei [[alternative HTML version deleted]]

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 value of `a` directly, why not changing the value of a duplicated `a`? So you do not have to

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, which will require that the ALTREP data is in memory. Is it on purpose? Will there be any plan to

Hi all, The coercion function defined for the ALTREP object will not be called by R when an assignment operation implicitly introduces coercion for a large ALTREP object. For example, If I create a vector of length 10, the ALTREP coercion function seems to work fine. ``` > x <- 1:10 > y <- wrap_altrep(x) > .Internal(inspect(y)) @0x000000001f9271c0 13 INTSXP g0c0 [REF(2)] I am
