deseason: Create seasonal anomalies

In environmentalinformatics-marburg/remote: Empirical Orthogonal Teleconnections in R

Create seasonal anomalies

Description

The function calculates anomalies of a RasterStack by supplying a suitable seasonal window. E. g. to create monthly anomalies of a raster stack of 12 layers per year, use cycle.window = 12.

Usage

## S4 method for signature 'RasterStackBrick'
deseason(x, cycle.window = 12L, use.cpp = FALSE, filename = "", ...)

## S4 method for signature 'numeric'
deseason(x, cycle.window = 12L)

Arguments

x	An Raster* object or, alternatively, a numeric time series.
cycle.window	integer, defaults to 12. The window for the creation of the anomalies.
use.cpp	logical, defaults to FALSE. Determines whether or not to use Rcpp functionality. Only applies if x is a Raster* object.
filename	character. Output filename (optional).
...	Additional arguments passed on to writeRaster, only considered if filename is specified.

Value

If x is a Raster* object, a deseasoned RasterStack; else a deseasoned numeric vector.

Examples

data("australiaGPCP")

aus_dsn <- deseason(australiaGPCP, 12)

opar <- par(mfrow = c(1,2))
plot(australiaGPCP[[1]], main = "original")
plot(aus_dsn[[1]], main = "deseasoned")
par(opar)
