Dear all,
I'm working on a code and I don't understand something probably related to
the writting rules of R
My code :
library(rgdal)
shp_paths = list.files(path = "X:/IGN/BDTOPO_V2.1", pattern
="TRONCON_COURS_EAU.SHP",
full.names = T,recursive = T,include.dirs = F)
shp_objects <- lapply(shp_paths, function(x) {readOGR(dsn=x,
layer=ogrListLayers(x))}) ### Liste de
SpatialLineDataFrames
"shp_objects" is a large list of 16 elements (192 Mb)
What I want to do is an union of these 16 elements.
Does anybody has a pist ?
Thanks !
Cheers
