Optimize rxode2 for computer evaluation

Description

This optimizes rxode2 code for computer evaluation by only calculating redundant expressions once.

Usage

rxOptExpr(x, msg = "model")

Arguments

x

rxode2 model that can be accessed by rxNorm

msg

This is the name of type of object that rxode2 is optimizing that will in the message when optimizing. For example "model" will produce the following message while optimizing the model:

finding duplicate expressions in model...
