Here are some of my R packages and other code I find well enough documented for sharing.

R-packages
My spatial statistics packages are suitable also for large datasets (n>100k). They are written in R and C++, using my own sparse matrix representation of local neighbourhoods.
- spatgraphs v.2.50:
For a given spatial point pattern, calculates a graph structure with several (12) different spatial relations. (CRAN) (demo) (intro)
- spatialsegregation v.2.34:
Spatial exposure measures (rainforest ecology). Latest version includes weighting ISAR values with e.g. phylogenetic distances between species. (CRAN).
- SGCS v.1.6:
Spatial Graph based Component Summaries for point processes analysis. (CRAN)(paper)
- Kolikonheitto v.0.3:
Toy I made for the university's Science day the other year. It collects coin tosses (upto 4 different coins simultaneously), and shows in graphics the confidence interval and Bayesian probability interval for the heads probability. Nice for showing little kiddies how the gathered information increases our confidence on the hidden truth. Has a nice GUI and everything.
Python
- Boolean disc random walkers: Made this to visualise the phase transition of boolean model, and to see if a graph related quantity, the connectivity number, describes the critical state. Requires the package pygame (zip)
- Image to point pattern: Estimate coordinates of "points" in a given picture using varius filters and center point estimation. Cumbersome to use but does the job on simple images, a bit heavy though. (zip) (I suggest ImageJ, much more advanced)
- Game Of Life: Interactive Conway's Game of Life simulator, mouse control and all. Press 'h' for key help. Needs pygame (see above)(tar.gz)
