Description

Create MxAlgebra object from a string

Usage

mxAlgebraFromString(algString, name = NA, dimnames = NA, ...)

Arguments

algString	the character string to convert into an R expression
name	An optional character string indicating the name of the object.
dimnames	list. The dimnames attribute for the algebra: a list of length 2 giving the row and column names respectively. An empty list is treated as NULL, and a list of length one as row names. The list can be named, and the list names will be used as names for the dimensions.
...	Forwarded verbatim to mxAlgebra

Examples

A <- mxMatrix(values = runif(25), nrow = 5, ncol = 5, name = 'A')
B <- mxMatrix(values = runif(25), nrow = 5, ncol = 5, name = 'B')
model <- mxModel(A, B, name = 'model',
  mxAlgebraFromString("A * (B + A)", name = 'test'))
model <- mxRun(model)
model[['test']]$result
A$values * (B$values + A$values)
