cellFromXY: Get cell number from row, column or XY
In rts: Raster Time Series Analysis

Description Usage Arguments Details Value Author(s) Examples

Get cell number(s) of a Raster*TS object from row and column numbers or X and Y coordinates.

1 2	cellFromRowCol(object, rownr, colnr) cellFromXY(object, xy)

`object`	a raster time series (`Raster*TS`) object created by `rts`
`colnr`	column number; or vector of column numbers
`rownr`	row number; or vector of row numbers
`xy`	matrix of x and y coordinates, or a SpatialPoints or SpatialPointsDataFrame object

These functions are essentially a wrapper to cellFromRowCol and cellFromXY in raster package, work with Raster*TS objects.

row, column or cell number(s). cellFromLine and cellFromPolygon return a list.
