When I think it may be helpful to others, I write my own code and publish it as a software package (including user manuals and all that). 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.
