Coding
R packages
I am the creator and maintainer of the following packages:
biotic. This calculates a range of common UK freshwater biotic indicies. The stable version (0.1.2) can be installed from CRAN. I am currently starting work on version 0.2. Follow progress, request a feature, log an issue or install the development version from Github.
cde. This is a package to facilitate download and analysis of WFD monitoring data from the Environment Agency Catchment Data Explorer website. The current version can be installed from github. This package is part of the rOpenSci family of packages.
Python
I use GIS in a lot of my work, mainly QGIS and R. I have used Python to develop some scripts and tools for various analyses, such as randomisation tests to determine the extent of clustering of marine invasive species around ports, import of data from the National Biodiversity Network (before they improved their output data format) and top-of-the atmosphere correction of Landsat images. Most of this is either too hacky to release or has been superceded by other tools. If I ever get round to sorting it out, then it will be made available on Github.
Visual Basic for Applications
I have developed a few add-ins for Excel using VBA. You can download these (zipped add-in files with outline instructions) below:
This calculates population estimates using the Carle & Strube and Zippen estimators
This calculates BMWP and associated indices for UK freshwater invertebrate samples. Now superceded by the biotic package above, but available for posterity!
