Dear expeRts, I want to read a a.tif file into R. When i try this: readGDAL("a.tif"), i get the following error: a.tif has GDAL driver GTiff and has 7200 rows and 7200 columns error: can't allocate 395.5 mb vector but i can GDAL.open("a.tif") it. SO what's wrong with readGDAL? -- PO SU mail: desolator88 at 163.com Majored in Statistics from SJTU
