I realized that if i use writeOGR from rgdal and not the other write shapefile functions i can get a shapefile with projection recognized by ArcGIS. The command is (in case anybody wonders): > > ?writeOGR(crest.sp, "I:\\LA_levee\\Shape", "llev_crest_pts6", driver = "ESRI Shapefile") > > where crest.sp is a spatial point data frame with projection. > > Thanks, > > Monica Indeed. writePoint

Indeed.

writePointsShape() does not write the projection file, but  using the 
function showWKT from rgdal, you can also create one like that:

writePointsShape(crest.sp,"crest")
cat(showWKT(proj4string(crest.sp)),file="crest.prj")
