replaceVariables: Replaces variables in a general graph with specified numeric values

Description

Given a list of variables and real values a general graph is processed and each variable replaced with the specified numeric value.

Usage

replaceVariables(
  graph,
  variables = list(),
  ask = TRUE,
  partial = FALSE,
  expand = TRUE,
  list = FALSE
)

Value

A graph or a matrix with variables replaced by the specified numeric values. Or a list of theses graphs and matrices if a variable had more than one value.

Arguments

graph: A graph of class graphMCP or class entangledMCP.
variables: A named list with one or more specified real values, for example list(a=0.5, b=0.8, "tau"=0.5) or list(a=c(0.5, 0.8), b=0.8, "tau"=0.5). If ask=TRUE and this list is missing at all or single variables are missing from the list, the user is asked for the values (if the session is not interactive an error is thrown). For interactively entered values only single numbers are supported.
ask: If FALSE all variables that are not specified are not replaced.
partial: IF TRUE only specified variables are replaced and parameter ask is ignored.
expand: Used internally. Don't use yourself.
list: If TRUE the result will always be a list, even if only one graph is returned in this list.
