growthmodels: Nonlinear Growth Models

growthmodels is a R package that contains a compilation of nonlinear growth models used in many areas.

Installation

To install the stable version of growthmodels from CRAN, simply run the following from an R console:

install.packages('growthmodels')

To install the latest development builds of growthmodels directly from GitHub, run this instead:

require(devtools) install_github('growthmodels', 'drodriguezperez')

Features

growthmodels includes functions for the calculation of the following nonlinear growth models and its inverse functions:

  • Blumberg
  • Brody
