An implementation of the Thornley transport resistance plant growth model. The package can be used to simulate plant growth as forced by climate system variables. The package provides methods for formatting forcing variables, simulating growth dynamics and calibrating model parameters. For more information see Higgins et al. (2025) TTR.PGM: An R package for modelling the distributions and dynamics of plants using the Thornley transport resistance plant growth model. Methods in Ecology and Evolution. in press.
Source code for the R package TTR.PGM. Running "R CMD build TTR.PGM" will build TTR.PGM_1.0.0.tar.gz, which may involve the time consuming task of building the vignettes (depending on what is in .Rbuildignore). The current default is to not build the vignettes. Running "R CMD check TTR.PGM_1.0.0.tar.gz" will also follow .Rbuildignore. Running "R CMD INSTALL TTR.PGM_1.0.0.tar.gz" will install the package, but does not build the vignettes.
