shift function

Shift

Shift the location of a Raster* of vector type Spatial* object in the x and/or y direction methods

## S4 method for signature 'Raster'
shift(x, dx=0, dy=0, filename='', ...)

## S4 method for signature 'SpatialPolygons'
shift(x, dx=0, dy=0,  ...)

## S4 method for signature 'SpatialLines'
shift(x, dx=0, dy=0,  ...)

## S4 method for signature 'SpatialPoints'
shift(x, dx=0, dy=0,  ...)

Arguments

• x: Raster* or Spatial* object
• dx: numeric. The shift in horizontal direction
• dy: numeric. The shift in vertical direction
• filename: character file name (optional)
• ...: if x is a Raster* object: additional arguments as for writeRaster

Returns

Same object type as x
