It was happening here too: https://github.com/ITSLeeds/slopes/issues/10#issuecomment-624030840
And I trimmed the road network, near the river, and it worked
I discarded some road segments from the 25k dataset (the ones that were pretty close to the DEM border, i.e, the river), and kept about 23k.
But anyway, if the whole network works with ArcMap, why not here? :)
I think it's because currently the package only works with LINESTRING geometries, as with #12:
network = sf::st_read("https://github.com/U-Shift/Declives-RedeViaria/blob/main/shapefiles/RedeViariaLisboa_dadosabertos.gpkg?raw=true")

Worth making it work with MULTILINESTRING objects? Don't think it's a priority and I think it makes more sense to calculate a slope for a single line geometry than multiple ones, so that restriction encourages people to break-up their network.
Great!!!! Yes, that new warning for cast is enough. Thanks :)

Another issue with
slope_raster
, that I'm having is that sometimes, after the function run completely, it had only computed slope value for the first 10-20 rows, leaving all the renaming ones asNA
