These functions get the row and/or column number from a cell number of a Raster* object)
Usage
colFromCell(object, cell)
rowFromCell(object, cell)
rowColFromCell(object, cell)
Arguments
- object
Raster* object (or a SpatialPixels* or SpatialGrid* object)
- cell
cell number(s)
Details
The colFromCell and similar functions accept a single value, or a vector or list of these values,
Cell numbers start at 1 in the upper left corner, and increase from left to right, and then from top to bottom.
The last cell number equals the number of cells of the Raster* object.
Value
row of column number(s)
Examples
r <- raster(ncols=10, nrows=10)
colFromCell(r, c(5,15))
#> [1] 5 5
rowFromCell(r, c(5,15))
#> [1] 1 2
rowColFromCell(r, c(5,15))
#> row col
#> [1,] 1 5
#> [2,] 2 5
