Hi, I have an issue. My ascii file (actually a .txt file) doesn't have a header. I can still load it in, and call it without issues (raster). however my plot is a grid 1x1 with a blank fill, so it looks like it doesnt find my parameters. I tried inserting them manually, but nothing changes.
Can you help me with that?
thanks!
