ApplySpace: Apply a function across space

In EarthSystemDiagnostics/pfields: An R Package to Analyse Gridded Field Data

Description

Apply a function across the spatial dimension of a "pField" or "pTs" object by using apply on the rows of the object. The result of this gives a "pTs" vector object, i.e. a single time series.

Usage

ApplySpace(data, FUN, ...)

Arguments

data	a "pField" or "pTs" object.
FUN	the function to be applied.
...	further arguments passed on to FUN.

Details

Input columns which only contain NA values are stripped befor applying the function. If only one non-NA column is present, this column is returned unchanged with a warning.

Value

a single "pTs" time series with the results of the function applied.

Examples

x <- pField(data = array(rnorm(10 * 10 * 100), dim = c(10, 10, 100)),
            time = 1 : 100, lat = 1 : 10, lon = 1 : 10)
ApplySpace(x, sd)

x <- x[, 1 : 15]
ApplySpace(x, sd)
