General Information on the variables Package
The variables package offers a small collection of objects describing conceptual variables and corresponding methods, for example for generating a grid of values for a (yet) unmeasured variable.
The package was written to support the basefun and mlt packages and will be of limited use outside these packages. The user interface is not yet stable, so please be careful using variables in your package.
