changeBounds: Change Variable Bounds in a Metabolic Network
In sybil: Efficient Constrained Based Modelling

Description Usage Arguments Details Value Author(s) See Also Examples

The function changes the upper and/or lower bounds of a given metabolic network model to new values.

1	changeBounds(model, react, lb = NULL, ub = NULL)

`model`	An object of class `modelorg`.
`react`	An object of class `reactId`, character or integer. Specifies the fluxes (variables) for which to change the upper and/or lower bounds.
`lb`	Numeric vector giving the lower bounds for the fluxes mentioned in `react`. If missing, lower bounds are set to zero. If `lb` has a length of 1, the value of `lb` will be used for all reactions in `react`.
`ub`	Numeric vector giving the upper bounds for the fluxes mentioned in `react`. If missing, upper bounds are set to zero. If `ub` has a length of 1, the value of `ub` will be used for all reactions in `react`.

The argument react will be evaluated by the function checkReactId.

Returns the given model (an object of the same class as the argument lpmodel) containing the new objective function.

  ## change the E.coli core model to lactate input:
  data(Ec_core)
  Ec_new <- changeBounds(Ec_core,
                         c("EX_glc", "EX_lac"),
                         lb = c(0, -20), ub = 1000)
