rescomp: Efficient Modelling of Resource Competition

Generate, simulate and visualise ODE models of consumer-resource interactions. At its core, 'rescomp' provides a resource competition modelling focused interface to 'deSolve', alongside flexible functions for visualising model properties and dynamics. More information, documentation and examples can be found on the package website.

rescomp: An R package for efficient ODE modelling of resource competition

Model formulation | Consumer equations | Resource equations | Using rescomp | Type 2 consumer on a logistically growing resource | Type 2 consumer on a continuously supplied resource | Two type 2 consumers on a logistically growing resource | Two type 1 consumers and two substitutable resources in a chemostat | Two type 1 consumers and two essential resources in a chemostat | Two type 2 consumers and one externally pulsed resource (continuous mortality) | Two type 2 consumers and one externally pulsed resource (serial transfer with pulsed mortality) | Two type 2 consumers with time dependent consumption parameters and one continuously supplied resource | Three type 1 consumers on three essential resources generating an intransitive loop (i.e. rock paper scissors dynamics).
