Thank you for the hints – I will test and report any surprises ☺

Subject: Re: [R-sig-Geo] Sf find number of parts in multigeometry
I see perfectly go
I see perfectly good answers to this, but can't resist sharing my own
approach.
I use gibble::gibble for a summary of parts. See how the multi-part
object is number 4, and has 3 subobjects (subobject will repeat within
object for holes).
library(sf)
x <- read_sf(system.file("gpkg/nc.gpkg",
As an addition to obrl soil's answer, I have come to like
lengths(st_geometry(x)) - mind the s!
Best

Hi Martin,
for a multipolygon geometry column, you're working with a list of
lists of lists of matrices, so you can iterate over the geometry
