## S4 method for signature 'Arena'
changeSub(object, smax, mediac, unit = "mmol/cell")

Arguments

object

An object of class Arena.

smax

A number or vector of numbers indicating the maximum substance concentration per grid cell.

mediac

A character vector giving the names of substances, which should be added to the environment (the default takes all possible substances).

unit

A character used as chemical unit to set the amount of the substances to be added (valid values are: mmol/cell, mmol/cm2, mmol/arena, mM)

Details

If nothing but object is given, then all possible substrates are initilized with a concentration of 0. Afterwards, changeSub can be used to modify the concentrations of specific substances.
