fluxVar: Flux Variability Analysis

Description Usage Arguments Details Value Author(s) References Examples

View source: R/fluxVar.R

Description

Performs flux variability analysis for a given model.

Usage

1
  fluxVar(model, react = c(1:react_num(model)), exex = FALSE, ...)

Arguments

model

An object of class modelorg.

react

An object of class reactId, character or integer. Specifies the fluxes (variables) to analyse.
Default: all reactions present in model.

exex

Boolean. Exclude exchange reactions from analysis. If set to TRUE, argument react will be ignored. All reactions present in model will be used, except for the exchange reactions.
Default: FALSE

...

Further arguments passed to optimizer. Argument algorithm is set to "fv", further possible arguments are fld, arguments for pre and post processing commands, verboseMode and further arguments passed to the constructor for objects of class sysBiolAlg_fv, see there for details.

Details

The algorithm is described in sysBiolAlg_fv.

Value

An object of class optsol_fluxVar. The first 1 to n (with n being the number of elements in argument react) solutions are from the minimizations, and the last n+1 to 2n solutions are from the maximizations.
