Description Usage Arguments Details Value Author(s)

It allows the user to define the polymerization condition trough graphycal menus and build the chemical-physical dataset

1	prepare(DBpp,DBk,recipe.inp, process.inp, flow.inp, interact=TRUE)

`DBpp`	chemical-physical properties database
`DBk`	kinetic constant database
`recipe.inp`	a vector with the previous user choice for the polymerization recipe
`process.inp`	a vector with the previous user choice for the process conditions
`flow.inp`	a vector with composition of in/out flow in case of continous polymerization
`interact`	logical, default=TRUE graphical menus are visualized for user choice

The function prepare the system for the following integration. It defines the recipe, the process and the flow conditions. It also picks up the chemical physical quantities from the internal database required to perform calculation. Its output is a list with vectors and functions built following the user choice in the graphical menus. In case the function is used for parameter determination, graphical menus are disabled setting interact=FALSE.
