The estar package provides two sets of functions.
The first set corresponds to functions that measure stability at any level of organisation, from individual to community and can be applied to a time series of a system’s state variables (e.g., body mass, population abundance, or species diversity). The properties included in this set are:
The second set of functions can be applied to Jacobian matrices. The functions in this set measure the stability of a community at short and long time scales. In the short term, you can measure:
In the long term, stability can be measured as:
The package includes two vignettes demonstrating the use of all functions, as well as a brief introduction to multivariate autoregressive state-space models necessary for the second set of metrics.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
