This function returns a data frame with the column number (x), row number (y) and cell value (z) of each pixel in a raster.
aue.image2df(mat, origin = c("upperleft", "lowerleft"), out = c("data.frame", "matrix"))
mat | Input raster matrix. |
---|---|
origin | Origin of the reference for the coordinates. Default: upperleft. |
out | output format: "data.frame" (default) or "matrix". |
