Announcing spopt-r: spatial optimization for regionalization, facility location, and market analysis in R. My all-time favorite Python package is PySAL's spopt - and until now, it did not have an R equivalent. Get started here: walker-data.com/spopt-r

great work as usual. It's using the rust interface to HiGHS?

yes it is!

as one who had a quick perusal in the R package, the rust crate automatically builds the high C++ directly so you don't need to have the library pre-installed! There's also a high-level crate too which is nifty crates.io/crates/good_lp

lol i think it's really just the call chain though... afaict the rust HiGHS interface is just a passthrough, and all the algos are *actually* written in C++ (i guess it's easier to bind r to rust, and rust to C++ than make r talk to c?). Feels like rust is almost a cython-like layer here
