zvalues function

Get or set z-values

Initial functions for a somewhat more formal approach to get or set z values (e.g. time) associated with layers of Raster* objects. In development.

setZ(x, z, name='time')
getZ(x)

Arguments

• x: Raster* object
• z: vector of z values of any type (e.g. of class 'Date')
• name: character label

Returns

setZ: Raster* object

getZ: vector

Examples

r <- raster(ncol=10, nrow=10)
s <- stack(lapply(1:3, function(x) setValues(r, runif(ncell(r)))))
s <- setZ(s, as.Date('2000-1-1') + 0:2)
s
getZ(s)
