...an example of the issue. emptyenv() can not be used, as it is needed for the eval (errors out even if weights are not used with "could not find function list"). For some applications one doesn't want the formula to have a non-trivial environment with respect to serialization. Nina Zumel wrote about reference leaks in lm()/glm() and a good part of that was environments other than global/base (such as those formed when building a formula in a function) capturing references to unrelated structures. > On Aug 10, 2020, at 11:34 AM, Duncan Murdoch <murdoch.duncan at gmail.com&g...

Dear R-devel, The most popular piping operator sits in the package `magrittr` and is used by a huge amount of users, and imported /reexported by more and more packages too. Many workflows don't even make much sense without pipes nowadays, so the examples in the doc will use pipes, as do the README, vignettes etc. I believe base R could have a piping operator so packages can use a pipe in

I wish I had started with "I am disappointed that lm() doesn't continue its search for weights into the calling environment" or "the fact that lm() looks only in the formula environment and data frame for weights doesn't seem consistent with how other values are treated." But I did not. So I do apologize for both that and for negative tone on my part. Simplified

First, thank you to Tomas for writing his recent post[0] on the R developer blog. It raised important issues in interfacing R's C API and C++ code. However I do _not_ think the conclusion reached in the post is helpful > don?t use C++ to interface with R There are now more than 1,600 packages on CRAN using C++, the time is long past when that type of warning is going to be useful to the
