When I think it may be helpful to others, I publish my code as a software package. So far, I have published two R packages on Github:

lorenzgini: generalized Gini for sparse data situations

Calculates the standard Gini coefficient as well as the generalized coefficient, and plots Lorenz curves. The Lorenz plots show the line of maximal equality given the data.

sppt: Spatial Point Pattern Test

Implements several area-based tests that measure the degree of similarity at the local level between two spatial point patterns.
