magpply: magpply

In magclass: Data Class and Tools for Handling Spatial-Temporal Data

magpply

Description

apply command for magpieobjects. Very efficient for replacing loops.

Usage

magpply(X, FUN, MARGIN = NULL, DIM = NULL, ..., INTEGRATE = FALSE)

Arguments

X	magpie object
FUN	function that shall be applied X
MARGIN	dimension over which FUN shall be applied (like a loop over that dimension). This dimension will be preserved in the output object (see also DIM).
DIM	dimension in which FUN shall be applied. This dimension will be missing in the output. DIM and MARGIN are opposite ways of expressing the dimensions to be addressed and you must only use one of them with MARGIN excluding dimensions from the calculation and DIM including them.
...	further parameters passed on to FUN
INTEGRATE	if TRUE, the output will be filled into an magpie object of the same dimensionality as X

Value

magpie object

Examples

pop <- maxample("pop")
magpply(pop, FUN = sum, MARGIN = 2)
fourdim <- pop * setNames(pop, c("jkk", "lk"))
magpply(fourdim, FUN = sum, MARGIN = c(1, 3.1))
