Identify the dimensions of an array over the size grid

Internal helper for sizeIntegral(). Returns a label for each dimension of x. The last dimension must run over the size grid and is labelled "w". Other dimensions are labelled from the names of their dimnames, if they have any, with "species" and "size" normalised to mizer's "sp" and "w". An unnamed second-to-last dimension is labelled "sp" if its extent is the number of species. Any remaining unnamed dimension gets a unique label of its own, so that it is carried through to the result rather than matched against a dimension of the abundance.

Usage

size_dim_labels(x, arg, no_sp, no_w)

Arguments

x

The array to label.

arg

The name of the argument holding x, used in error messages.

no_sp

The number of species in the model.

no_w

The number of size bins in the model.

Value

A character vector with one label for each dimension of x.

Details

A scalar has no dimensions and gets no labels.
