Hi All,
I read a lot about loop formula but this morning I tried to applied the loop
for the following formulas
I know it's easy for an expertise, but sorry I am working with R in this
mounts and I change completely my GIS philosophy.
Thanks for help
give a coordinates attribution
coordinates(centre_plot1) =~X+Y
coordinates(centre_plot2) =~X+Y
coordinates(centre_plot3) =~X+Y
coordinates(centre_plot4) =~X+Y

(I HAVE 500 plot)
proj4string(centre_plot1) <- CRS("+init=epsg:26911")
proj4string(centre_plot2) <- CRS("+init=epsg:26911")
proj4string(centre_plot3) <- CRS("+init=epsg:26911")
proj4string(centre_plot4) <- CRS("+init=epsg:26911")
writeOGR(centre_plot1 ["Z"], " centre_plot1.shp", " centre_plot1",
driver="ESRI Shapefile")
writeOGR(centre_plot2 ["Z"], " centre_plot2.shp", " centre_plot2",
driver="ESRI Shapefile")
writeOGR(centre_plot3 ["Z"], " centre_plot3.shp", " centre_plot3",
driver="ESRI Shapefile")
writeOGR(centre_plot4 ["Z"], " centre_plot4.shp", " centre_plot4",
driver="ESRI Shapefile")
