optsol_robAna-class: Class "optsol_robAna"

Description

Structure of the class "optsol_robAna". Objects of that class are returned by the function robAna.

Objects from the Class

Objects can be created by calls of the form new("optsol_robAna", ...).

Slots

ctrlr:

Object of class "reactId" containing the reaction id of the control reaction.

ctrlfl:

Object of class "numeric" containing the control flux values.

preProc:

Object of class "ppProc" containing the results of pre-processing. See also optimizeProb.

postProc:

Object of class "ppProc" containing the results of post-processing. See also optimizeProb.

mod_id:

Object of class "character" containing the model id of the used model.

mod_key:

Object of class "character" containing the model key of the used model.

solver:

Object of class "character" indicating the used solver.

method:

Object of class "character" indicating the used method.

algorithm:

Object of class "character" containing the name of the algorithm used for optimizations.

num_of_prob:

Object of class "integer" indicating the number of optimization problems.

lp_num_cols:

Object of class "integer" indicating the number of columns.

lp_num_rows:

Object of class "integer" indicating the number of rows.

lp_obj:

Object of class "numeric" containing the optimal values of the objective function after optimization. If no flux distribution is available, slot lp_obj contains the cross-product of the objective coefficients in slot obj_coef and the part of the flux distribution in slot fluxdist containing the values representing fluxes in the entire metabolic network (slot fldind).

lp_ok:

Object of class "integer" containing the exit code of the optimization.

lp_stat:

Object of class "integer" containing the solution status of the optimization.

lp_dir:

Object of class "character" indicating the direction of optimization.

obj_coef:

Object of class "numeric" containing the objective coefficients of the used model (slot obj_coef of an object of class '>modelorg). These are not necessarily the objective coefficients of the used algorithm.

obj_func:

Object of class "character" containing the objective function of the used model. Usually, it contains the return value of printObjFunc.

fldind:

Object of class "integer" pointers to columns (variables) representing a flux (reaction) in the original network. The variable fldind[i] in the problem object represents reaction i in the original network.

fluxdist:

Object of class "fluxDistribution" containing the solutions flux distributions.

alg_par:

Object of class "list" containing a named list containing algorithm specific parameters.

Extends

Class "'>optsol_optimizeProb", directly. Class "'>optsol", by class "optsol_optimizeProb", distance 2.

Methods

ctrlfl:

signature(object = "optsol_robAna"): gets the ctrlfl slot.

ctrlfl<-:

signature(object = "optsol_robAna"): sets the ctrlfl slot.

ctrlr:

signature(object = "optsol_robAna"): gets the ctrlr slot.

ctrlr<-:

signature(object = "optsol_robAna"): sets the ctrlr slot.

plot

signature(x = "optsol_robAna", y = "missing") (xlab = paste("Control Flux:", react_id(ctrlr(x))), ylab = paste("Objective Function:", obj_func(x)), type = "b", pch = 20, fillColorBg = "grey", fillBg = TRUE, absCtrl = TRUE, ...): plots the optimal values of the objective function vs. the control flux values.

xlab

label of x-axis, see also par.

ylab

label of y-axis, see also par.

type

plot type, see also par.

pch

how to plot the points, see also par.

fillColorBg

color of the area below the curve.

fillBg

logical: color the area below the curve.

absCtrl

if set to TRUE, the control flux values (x axis) are plotted as absolute values.

...

further graphical parameters to the points function.
