An object of class '>reactId, character or integer.
Specifies the fluxes (variables) for which to change the objective
coefficients.
obj_coef
A numerical vector with length equal to the number of reaction id's
given in argument react containing the objective coefficients.
Default: a value of one for each reaction given in argument react.
Value
Returns the given model containing the new objective function.
Details
The argument react will be evaluated by the function
checkReactId. The return value is used to change
the objective function.
All reactions not given in argument react will get an objective
value of zero.
