ipmr

Flexibly implements Integral Projection Models using a mathematical(ish) syntax. This package will not help with the vital rate modeling process, but will help convert those regression models into an IPM. 'ipmr' handles density dependence and environmental stochasticity, with a couple of options for implementing the latter. In addition, provides functions to avoid unintentional eviction of individuals from models. Additionally, provides model diagnostic tools, plotting functionality, stochastic/deterministic simulations, and analysis tools. Integral projection models are described in depth by Easterling et al. (2000) [doi:10.1890/0012-9658(2000)081[0694:SSSAAN]2.0.CO;2](https://doi.org/10.1890%2F0012-9658%282000%29081%5B0694%3ASSSAAN%5D2.0.CO%3B2), Merow et al. (2013) doi:10.1111/2041-210X.12146, Rees et al. (2014) doi:10.1111/1365-2656.12178, and Metcalf et al. (2015) doi:10.1111/2041-210X.12405. Williams et al. (2012) doi:10.1890/11-2147.1 discuss the problem of unintentional eviction.
