Software

I am the author of sisal, an input selection package for R.

I have contributed to the development of dplR, a tree-ring analysis package for R.

Smaller piece(s) of R code written by me may be found at GitHub. A colorbar implementation is included.

A script for creating printable name tags can also be downloaded from GitHub.

I wrote an enhancement addressing missing features in parts of the I/O subsystem of R. The patch was not included in the R distribution, but anyone interested in using seek() with a non-default encoding may want to take a look at my proposed solution. Before including my code in your self-compiled R, be sure to examine its compatibility with the version of R you are using and make any necessary adjustments.
