Generates and evaluates D, I, A, Alias, E, T, and G optimal designs. Supports generation and evaluation of blocked and split/split-split/.../N-split plot designs. Includes parametric and Monte Carlo power evaluation functions, and supports calculating power for censored responses. Provides a framework to evaluate power using functions provided in other packages or written by the user. Includes a Shiny graphical user interface that displays the underlying code used to create and evaluate the design to improve ease-of-use and make analyses more reproducible. For details, see Morgan-Wall et al. (2021) <doi:10.18637/jss.v099.i01>.

A tool to calculate sky illuminance values (in lux) for both sun and moon. The
 model is a translation of the Fortran code by Janiczek and DeYoung (1987)
 <https://archive.org/details/DTIC_ADA182110>.

Calculate geolocations by light using template matching. 
 The routine uses a calibration free optimization of a sky illuminance model to 
 determine locations robustly using a template matching approach,
 as described by Ekstrom (2004) <https://nipr.repo.nii.ac.jp/records/2496>,
 and behaviourly informed constraints (step-selection).

'Slack' <https://slack.com/> provides a service for teams to
    collaborate by sharing messages, images, links, files and more.
    Functions are provided that make it possible to interact with the
    'Slack' platform 'API'. When you need to share information or data
    from R, rather than resort to copy/ paste in e-mails or other services
    like 'Skype' <https://www.skype.com/en/>, you can use this package to
    send well-formatted output from multiple R objects and expressions to
    all teammates at the same time with little effort. You can also send
    images from the current graphics device, R objects, and upload files.

Data structures and algorithms for sparse arrays and matrices,
  based on index arrays and simple triplet representations, respectively.

Slanted matrices and ordered clustering for better visualization of similarity data.
