Replaces variables in a general graph with specified numeric values

Source: R/misc.R
replaceVariables.Rd

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
)

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.

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.
