ArrayTimeByResourceBySize: S3 class for time x resource-size arrays

Description

The NResource() function returns a two-dimensional array (time x size) holding the resource number density through time. The ArrayTimeByResourceBySize class wraps this array to provide convenient print(), summary(), plot(), and as.data.frame() methods.

Usage

ArrayTimeByResourceBySize(x, value_name = NULL, units = NULL, params = NULL)
is.ArrayTimeByResourceBySize(x)

Value

An ArrayTimeByResourceBySize object (inherits from matrix and array).

is.ArrayTimeByResourceBySize() returns TRUE if x is an ArrayTimeByResourceBySize object, FALSE otherwise.

Arguments

x

A matrix (time x size). For is.ArrayTimeByResourceBySize(), any object to test.

value_name

A string giving the human-readable name for the value.

units

A string giving the units (e.g. "1/g").

params

A MizerParams object. Used for the resource colour and the size grid in the plot() method.

Details

An ArrayTimeByResourceBySize object behaves just like a regular matrix for arithmetic operations and subsetting. It carries these lightweight attributes:

• value_name – a human-readable name for the value (e.g. "Number density").

• units – the units of the value (e.g. "1/g").

• params – the MizerParams object that the value was computed from.

Examples

# \donttest{
nr <- NResource(NS_sim)
is.ArrayTimeByResourceBySize(nr)
summary(nr)
plot(nr)
# }
