tidysdm - Species Distribution Models with Tidymodels

Fit species distribution models (SDMs) using the 'tidymodels' framework, which provides a standardised interface to define models and process their outputs. 'tidysdm' expands 'tidymodels' by providing methods for spatial objects, models and metrics specific to SDMs, as well as a number of specialised functions to process occurrences for contemporary and palaeo datasets. The full functionalities of the package are described in Leonardi et al. (2023) <doi:10.1101/2023.07.24.550358>.

admixtools - Inferring demographic history from genetic data

admixtools is a set of methods used to infer demographic history from genetic data using f-statistics. It was originally implemented as a command line program in C. This is a new implementation of the programs qpDstat, qpAdm, qpGraph, and contains several new features. It is efficient because it precomputes f2-statistics which can be re-used for many analyses.
