lagalize: Create lagged RasterStacks

In remote: Empirical Orthogonal Teleconnections in R

Description

The function is used to produce two lagged RasterStacks. The second is cut from the beginning, the first from the tail to ensure equal output lengths (provided that input lengths were equal).

Usage

lagalize(x, y, lag = NULL, freq = 12, ...)

Arguments

x	a RasterStack (to be cut from tail)
y	a RasterStack (to be cut from beginning)
lag	the desired lag (in the native frequency of the RasterStack)
freq	the frequency of the RasterStacks
...	currently not used

Value

a list with the two RasterStacks lagged by lag

Examples

data(pacificSST)
data(australiaGPCP)

# lag GPCP by 4 months
lagged <- lagalize(pacificSST, australiaGPCP, lag = 4, freq = 12)
lagged[[1]][[1]] #check names to see date of layer
lagged[[2]][[1]] #check names to see date of layer
