Cannot open shapefile in R
0
I am not sure why but I cant read shapefiles at all in r!
On a MacOS Mojave,
I have tried:
afg <- readOGR("afg.shp")
afg <- readOGR(dsn = ".", layer = "afg")
The shapefiles are from this website: http://www.diva-gis.org/gdata, Afghanistan roads.
This same error keeps occuring:
Error in ogrInfo(dsn = dsn, layer = layer, encoding = encoding, use_iconv = use_iconv, :
Cannot open layer
However, this code works:
countries <- readOGR("countries.geojson")
Can someone figure out why?

Maybe you need to specify the path to the shapefile? If you unzipped to create the directoryAFG_rdsinDownloads, this should work:readOGR("~/Downloads/AFG_rds/AFG_roads.shp")

Works for me too. Not sure why the file name in the question isafg.shp; this is not the file name in the download.
