Lap: LST of a Node

Description

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

Usage

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

Arguments

code

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

structure

object of class Mother (the structure).

outVar

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

par

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

Value

A character string giving the 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'.

# NOT RUN {
structure <- GEO(0.1, NULL, list(GAMMA(0.1, 1:2, NULL),
                           GAMMA(0.2, 3:4, NULL)))

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