Example
We can illustrate the three modules of the EWSmethods package
using one of the two datasets bundled with the package: simsTransComms. simsTransComms contains three
replicate communities of five species each, simulated from a competitive
Lotka-Volterra model following Dakos (2018). Each community is driven
through a tipping point by increasing the carrying capacity of a low
density species which mimics the appearance of an invasive species in
the community. The time index of the tipping points is provided in the
inflection_pt column. It is key to truncate this data set to only
contain data prior to this tipping point for EWSs to have any meaningful
value as a sentinel of transition (Dale and Beyeler 2001, Gsell et al.
2016). This can be achieved using the inflection_pt column of the simTransComms$‘1_5_1‘ community.
