BacArena (version 1.0.1)

growth: Function implementing a growth model of a bacterium

Description

The generic function growth implements different growth models for an object of class Bac.

Usage

growth(object, population, j)
"growth"(object, population, j)

Arguments

object

An object of class Bac.

population

An object of class Arena.

j

The number of the iteration of interest.

Value

Boolean variable of the jth individual indicating if individual died.

Details

Linear growth of organisms is implemented by adding the calculated growthrate by optimizeLP to the already present growth value. Exponential growth of organisms is implemented by adding the calculated growthrate multiplied with the current growth calculated by optimizeLP plus to the already present growth value

Examples

data(Ec_core, envir = environment()) #get Escherichia coli core metabolic model
bac <- Bac(Ec_core,deathrate=0.05,
           growthlimit=0.05,growtype="exponential") #initialize a bacterium
arena <- Arena(n=20,m=20) #initialize the environment
addOrg(arena,bac,amount=10) #add 10 organisms
addSubs(arena,40) #add all possible substances
growth(bac,arena,1)
