Rotate

Description

Rotate a Raster* object that has x coordinates (longitude) from 0 to 360, to standard coordinates between -180 and 180 degrees. Longitude between 0 and 360 is frequently used in global climate models.

Usage

## S4 method for signature 'Raster'
rotate(x, filename='', ...)

Arguments

`x`	Raster* object
`filename`	character. Output filename (optional)
`...`	additional arguments as for `writeRaster`

Value

RasterLayer or a RasterBrick object

Examples

r <- raster(nrow=18, ncol=36)
m <- matrix(1:ncell(r), nrow=18)
values(r) <- as.vector(t(m))
extent(r) <- extent(0, 360, -90, 90)
rr <- rotate(r)
