A set of tools to analyze and model leaf gas exchange data, such as fitting A-Ci curves or simulating from a coupled leaf gas exchange model. Visit the repository here, with installation instructions and examples. The package is also on CRAN. Read the open-access publication on PLOS One describing the package.
Together with Jeff Powell, I have developed this book on 'Data analysis and visualization with R', used to teach an R course at the Hawkesbury Institute for the Environment. The book is written in Latex, embedding R code using the knitr package. You can download the PDF free of charge here or browse the source code here (provided under the GPL-2 license).
An R package to fit hydraulic vulnerability curves to measurements of conductivity or PLC and water potential. Uses the bootstrap to estimate confidence intervals on the fitted curve and the parameters (P50 etc.). Read our open-access publication describing the package here. Visit the repository here, with installation instructions and examples.
I have developed this new version of Yplant in collaboration with Mik Cieslak. This model calculates light interception on each leaf of a digitized plant, accounting for transmission and scattering of light. Read the Prometheus wiki on Yplant here. The model is available as an R package on CRAN, or visit the code repository here.
I maintain the code of the revamped smatr R package, developed by David Warton, Daniel Falster and others. We have published this package as well. This tool is often used in studies of plant and animal allometry. It has even been cited by a study on the exploration of Mars.
