move: Function for random movement of organisms

In euba/BacArena: Modeling Framework for Cellular Communities in their Environments

Function for random movement of organisms

Description

The generic function move implements a random movement in the Moore neighbourhood of an individual.

Usage

move(object, pos, n, m, j, occupyM)

## S4 method for signature 'Organism'
move(object, pos, n, m, j, occupyM)

Arguments

object	An object of class Organism.
pos	A dataframe with all occupied x and y positions
n	A number giving the horizontal size of the environment.
m	A number giving the vertical size of the environment.
j	The number of the iteration of interest.
occupyM	A matrix indicating grid cells that are obstacles

Details

Organisms move in a random position the Moore neighbourhood, which is not occupied by other individuals. If there is no free space the individuals stays in the same position.

Examples

data(Ec_core, envir = environment()) #get Escherichia coli core metabolic model
bac <- Bac(Ec_core,deathrate=0.05,
           minweight=0.05,growtype="exponential") #initialize a bacterium
arena <- Arena(n=20,m=20) #initialize the environment
arena <- addOrg(arena,bac,amount=10) #add 10 organisms
arena <- addSubs(arena,40) #add all possible substances
move(bac,n=20,m=20,j=1,pos=arena@orgdat[,c('x','y')], occupyM=arena@occupyM)
