...t a package. But it seems that something changed quite recently in R. I looked into this a little yesterday and prepared a workaround for Rcpp; Kevin (CC'ed) was more diligent and found what changed with R itself. See the discussion under issue ticket #1087 at the Rcpp repo: https://github.com/RcppCore/Rcpp/issues/1087 The proposed simple PR is at https://github.com/RcppCore/Rcpp/pull/1088 As Kevin mentions in #1087, R itself may have changed, and he even dug up a possible commit [1]. One can illustrate that quickly with two different R interpreters, I use Docker here because that's what I o...

...g Rcpp. I'm also curious about this sentence from the doc: "In the future R may provide some automated tools to simplify exporting larger numbers of routines." Is there a draft of something ? Romain For details on how we will be using LinkingTo. Please see: https://github.com/RcppCore/Rcpp/blob/master/inst/include/Rcpp/routines.h where depending - when we are compiling Rcpp, we just have a declaration of the function, which is then defined in any of our .cpp files. - when we are using Rcpp from another package, we are retrieving the function https://github.com/RcppCore/Rcpp/...

Hello,?I?am experiencing some difficult time with my R package. Every time I compilei it a hidden file, desktop.ini, is?being created. I am using C++ behind, linkking to Rcpp. The file is generated even when I compile it with?Linux, and in many different computers. Does anybody have any advice or ideas?

Hi, I am trying to remove key-value pairs from an environments (using C). While adding seems straightforward with `Rf_defineVar()`, I cannot find a function to remove objects from a given environment. Would anyone know if there is such a function ? Best, Laurent

Hi I tried to use Michael's ppa after having installed Ubuntu 20.04 and R 4, and it seems the ppa is not available now for 20.04, I get message: The repository 'http://ppa.launchpad.net/marutter/c2d4u3.5/ubuntu focal Release' does not have a Release file Am I doing something wrong, or is it correct that it is not available yet? Are there any plans to implement it at some point?

...ork in practice. Ask Uwe one day we he rebuilds everything every time on Windows. And for what it is worth, we essentially do the same in Debian. Sometimes you just need to rebuild. That may be the price of admission for using the convenience of rich C++ interfaces.

Hi I'd like to suggest to make R more informative when a user updates a package A where there's at least one package B that has "LinkingTo: A" in its description. To illustrate the problem, assume package A is updated so that its C/C++ header interface (in inst/include) is changed. For package B to pick up these changes, we need to reinstall package A. In extreme cases, if
