Setup {LIM}R Documentation

Creates linear inverse matrices

Description

Creates the linear problem with equality and inequality equations.

Takes as input either a liminput list, as generated by Read or a filename with the linear inverse model specifications. Creates:

Usage

Setup(...)
Setup.limfile(file, verbose=TRUE, ...)
Setup.character(...)
Setup.liminput(liminput,...)

Arguments

file name of the inverse input file.
verbose if TRUE: prints warnings and messages to the screen.
liminput list of elements, as returned by Read.
... extra parameters allowing this to be a generic function.

Value

a list containing:

file name of the inverse input file.
NUnknowns number of unknowns.
NEquations number of equations.
NConstraints number of constraints.
NComponents number of components.
NExternal number of externals.
NVariables number of variables.
A matrix A of equalities Ax=B.
B vector B of equalities Ax=B.
G matrix G of inequalities Gx>h.
H vector H of inequalities Gx=h.
Cost cost vector (to minimise), the weight of each unknown; if not specified; 1 for all unknowns.
Profit profit vector (to maximise).
Flowmatrix matrix where element ij denotes flow from compartment i to j.
VarA matrix VarA of variable equation VarA*x=VarB.
VarB vector VarB of variable equation VarA*x=VarB.
Flows a vector with flow names.
Parameters a data.frame with parameter names and values.
Components a data.frame with state names and values.
Externals a data.frame with external names and values.
rates a data.frame with rate names and values.
markers a data.frame with marker names and values.
Variables a vector with variable names.
Unknowns a vector with names of unknowns (either states or flows).
Weight a vector with the weights of unknowns- default is 1.
