extend

Extend a magpie object to a dense grid based on the given xRange, yRange and resolution. This is e.g. required when writing netCDF files. Extending a sparse magpie object to a dense grid requires much more memory, so use with caution.

Usage

extend(x, gridDefinition = NULL, crop = FALSE)

Arguments

x

A magpie object

gridDefinition

A vector of 5 numeric values: c(xMin, xMax, yMin, yMax, resolution). Use c(-179.75, 179.75, -89.75, 89.75, 0.5) to extend to a standard 0.5-degree-resolution lon/lat grid. If NULL, use min/max of coordinates in x and guessResolution.

crop

If TRUE, discard cells from x which are not in the gridDefinition grid. If FALSE, throw an error if the coordinates of x are not a subset of the extended coordinates.

Value

Magpie object x with dense grid according to gridDefinition, gaps filled with NA.
