import ASCII file via RGDAL to SpatialPixelsDataFrame'
Try:
Zone_2644149 = readGDAL("Zone_2644149.asc")
This returns a SpatialGridDataFrame.Then:
fullgrid(Zone_2644149) = FALSE
converts into a SpatialPixelsDataFrame, or, in a single command:
Zone_2644149 = as(readGDAL("Zone_2644149.asc"), "SpatialPixelsDataFrame")

Dear R user,

to do some analisys. I am using like help
Zone_2644149 = readGDAL("Zone_2644149.asc")$band1
Zone_2644149.asc has GDAL driver AAIGrid
and has 246 rows and 381 columns
str(Zone_2644149)
num [1:93726] 35.1 34.7 35.2 35.9 31.2 ...
but I need to have a SpatialPixelsDataFrame but SORRY I haven't idea how to
import as SpatialPixelsDataFrame
