indexDatacube: Create logical index matrices for multidimensional datacubes

In ncdf.tools: Easier 'NetCDF' File Handling

Description

This function facilitates supplying logical index array for only some but not all of the dimensions of a data array. This mimics Matlabs indexing scheme. The indexing mechanisms of R only allow supplying logical indices for all dimensions.

Usage

indexDatacube(datacube = c(), logical.ind, dims = "auto", dims.datacube = dim(datacube))

Arguments

datacube	array: datacube from which to extract the sub-parts datacube and dims.datacube should be supplied.
logical.ind	logical array: TRUE/FALSE index matrix for a subset of the dimensions of the datacube. The size of logical.ind's dimensions has to match the sizes of the corresponding dimensions in datacube.
dims	integer vector or 'auto' : indices of the dimensions in datacube corresponding to the dimensions of logical.ind. If set to 'auto' this matching is tried to be accomplished by comparing the sizes of the dimensions of the two objects.
dims.datacube	integer vector: dimensions of the datacube. Only one of dims.datacube or datacube should be supplied!

Value

integer index matrix which can be used to index datacube
