Which could form a basis for thinking about an actual addition to the

Thanks Duncan and Ivan for the careful thoughts. I'm not sure I can follow
all aspects you raised, but to give my limited take on a few:

Dear R Core,
working on my dynamic factor modelling package, which requires several
subroutines to create and update several system matrices, I come back to
the issue of being annoyed by R not supporting multiple assignment out of
the box like Matlab, Python and julia. e.g. something like
A, C, Q
Dear R Core,
The {kit} package has a nice set of parallel statistical functions
complimenting base R's pmin() and pmax(): psum(), pprod(), pmean(), etc..
These can be called on a set of vectors like pmin() and pmax() e.g.
with(mtcars, psum(mpg, carb, wt)) or on a single list of vectors e.g.
psum(
a sum

Hello together, I'm working on some custom (grouped, weighted) sum, min and
max functions and I want them to support the special case of plain integer
sequences using ALTREP. I thereby encountered some behavior I cannot
explain to myself. The head of my fsum C function looks like this (g is

Hi together,
a bit more than a month ago I have released the 'collapse' package for
advanced and fast data transformation in R with an array of fast grouped
and weighted functions and facilities for efficient grouped programming in
R.
As I am preparing the next update of this package I have come
