primer 1.2.0

There are a lot of changes from June 2020, and even since October 2020. See the new draft of the Primer of Ecology Using R for updated text and code (31 Dec 2020).

Added

• Logistic growth ODEs: now there are three more similar functions, ‘dlogistic’, ‘clogistic’, and ‘alogistic’ that all use ‘ode()’ to solve them (see help pages for details!). These refer to discrete, continuous, and Allee effect (continuous logsitic).
• ‘bip_stability()’ calculates a variety of properties of mutualistic and antagonistic bipartite networks.
• New datasets (‘coneflower’, etc.) for use in an IPM (integral projection model) in Chap. 4 (density-independent demography).
• New functions related to generating 1/f environmental noise using any arbitrary set of numbers via spectral mimicry (‘spec_mimic()’, ‘one_over_f()’, ‘plot_f()’). I have plans to eventually include these in the end of chapter three (density-independent growth) in stochatic simulations.

Removed

• ‘DemoInfo()’ is no longer available. If you would like that code, I can send it to you.

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.
