In SpaDES.core: Core Utilities for Developing and Running Spatially Explicit Discrete Event Models

Check for existence of object(s) referenced by a objects slot of a simList object

Description

Check that a named object exists in the provide simList environment slot, and optionally has desired attributes.

Usage

checkObject(sim, name, object, layer, ...)

## S4 method for signature 'simList,missing,Raster,character'
checkObject(sim, name, object, layer, ...)

## S4 method for signature 'simList,missing,ANY,missing'
checkObject(sim, name, object, layer, ...)

## S4 method for signature 'simList,character,missing,missing'
checkObject(sim, name, object, layer, ...)

## S4 method for signature 'simList,character,missing,character'
checkObject(sim, name, object, layer, ...)

## S4 method for signature 'missing,ANY,missing,ANY'
checkObject(sim, name, object, layer, ...)

Arguments

sim	A simList() object.
name	A character string specifying the name of an object to be checked.
object	An object. This is mostly used internally, or with layer, because it will fail if the object does not exist.
layer	Character string, specifying a layer name in a Raster, if the name is a Raster* object.
...	Additional arguments. Not implemented.

Value

Invisibly return TRUE indicating object exists; FALSE if not.
