Access ‘Meetup’ API (meetupapi)
Allows management of ‘Meetup’ groups via the <h…/>. Provided are a set of functions that enable fetching information of joined meetups, attendance, and members. This package requires the use of an API key.

Causal Effects from Observational Studies with Clustered Interference (clusteredinterference)
Estimating causal effects from observational studies assuming clustered (or partial) interference. These inverse probability-weighted estimators target new estimands arising from population-level treatment policies. The estimands and estimators are introduced in Barkley et al. (2017) <arXiv:1711.04834>.

Fit a Stochastic Dynamical Array Model to Array Data (dynamo)
An implementation of the method proposed in Lund and Hansen (2018) for fitting 3-dimensional dynamical array models. The implementation is based on the glamlasso package, see Lund et al. (2017) <doi:10.1080/10618600.2017.1279548>, for efficient design matrix free lasso regularized estimation in a generalized linear array model. The implementation uses a block relaxation scheme to fit each individual component in the model using functions from the glamlasso package.

Item Based Collaborative Filtering for Multi-Trait and Multi-Environment Data (IBCF.MTME)
Implements the Item based collaborative filtering (IBCF) method for continues phenotypes in the context of plant breeding where data are collected for various traits that were studied in various environments proposed by Montesinos-López et al. (2017) <doi:10.1534/g3.117.300309>.

Helper Methods for ‘simmer’ Trajectories (simmer.bricks)
Provides wrappers for common activity patterns in ‘simmer’ trajectories.
