[Rd] base::order making available retGrp and sortStr options for radix method?

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

[Rd] ALTREP ALTINTEGER_SUM/MIN/MAX Return Value and Behavior

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

[Rd] pmin() and pmax() should process a single list of vectors, rather than returning it

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.

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: > your proposal violates a very basic property of the language, i.e. that all > statements are expressions and have a value. > What's the value of 1 + (A, C =

[Rd] Multiple Assignment built into the R Interpreter?

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,
