umx_string_to_algebra

Convert a string to an OpenMx algebra


Description

This is useful use to quickly and easily insert values from R variables into the string (using paste() and rep() etc.), then parse the string as an mxAlgebra argument.

Usage

umx_string_to_algebra(algString, name = NA, dimnames = NA)

Arguments

algString

a string to turn into an algebra

name

of the returned algebra

dimnames

of the returned algebra

Details

A use case is including a matrix exponent (that is A %% A %% A %*% A...) with a variable exponent.
