[R-sig-Geo] Error when saving an sf (data) object to file as a shapefile

[Lom Navanyo]

I have write permission to the folder. I have also now called the raster
package, coerced the sf object to Spatial and could save as a shapefile.
But just as you hinted and was further explained by Edzer and Tim, the
shapefile could not be used elsewhere.

Thank you all for the support.
