The WoodSimulatR package has been developed in the project InnoGrading by Holzforschung Austria (https://www.holzforschung.at).
It provides tools for generating simulated sawn timber strength grading data.
The main focus is statistical simulation based on covariance matrices.
WoodSimulatR also contains pre-stored simulation data for Norway spruce (Picea abies) sawn timber from Austria and reference values of means and standard deviations of grade determining properties (GDPs) from literature for a number of European countries.
You can install the released version of WoodSimulatR from CRAN with:
The most important use cases are explained in the vignette woodsimulatr_basics which can be accessed by:
The project InnoGrading was funded by the Austrian Research Promotion Agency (FFG; project nr. 869170).
The package WoodSimulatR was inspired by the work of Ranta-Maunus and Turk (2010).
Ranta-Maunus, Alpo, and Goran Turk. 2010. “Approach of Dynamic Production Settings for Machine Strength Grading.” In 11th World Conference on Timber Engineering 2010 (WCTE 2010), edited by A. Ceccotti and Jan-Willem G. van de Kuilen.
