InvLap: Inverse LST of a Node

Description

With a specific path and a predefined structure (S4 class of a type 'Mother'), returns the inverse Laplace-Stieltjes Transform expression of the corresponding node with a specific variable.

Usage

InvLap(code, structure, outVar = "z", par = "value")

Arguments

code

the genetic code (numeric vector) of the node (can be a leaf i.e. end by 0).

structure

an object of class Mother (the structure).

outVar

the output variable to be used ('z' by default).

par

logical. Should the parameters be values ('value') or variables ('variable') ?

Value

A character string giving the inverse LST of the specified node.

Details

For mother nodes, parameters are always called 'gamma' and for child nodes, parameters are always called 'alpha'. Furthermore, to recognize the parameters, the path is inserted at the end. For exemple, a child node with path (0,2,1) will have the parameter 'alpha021'.

structure <- GEO(0.1, NULL, list(GAMMA(0.1, 1:2, NULL),
                           GAMMA(0.2, 3:4, NULL)))

InvLap(c(0,2), structure, outVar = 'z', par = 'value')
