Dear all, Is it possible to import Esri ascii files which are compressed in a .gz file direct to R? My example : 111212.asc in an .gz File I thought there might be a similar command as the "zip.file.extract"- command. I tried the "gzfile" command, but it did not work. Do you have any suggestions?
The readGDAL command in rgdal needs a file, I believe, as also does readAsciiGrid() in maptools. The header is part of the same file, so it needs to be read in different ways, first to get the metadata, then to read the data.
