-This R package was developed for the [DenMod project](https://synergy.st-andrews.ac.uk/denmod/) (Working group for the advancement of marine species density surface modelling), and was funded by OPNAV N45 and the SURTASS LFA Settlement Agreement, being managed by the U.S. Navy’s Living Marine Resources program under Contract No. N39430-17-C-1982. The sperm whale data showcased in the [online vignette](https://densitymodelling.github.io/dsmextra/articles/dsmextra-vignette.html) were provided by Debi Palka (NOAA North East Fisheries Science Center) and Lance Garrison (NOAA South East Fisheries Science Center). Initial data processing was undertaken by Jason Roberts (Marine Geospatial Ecology Lab, Duke University).

-### Important note
-
-**May 2020**
-
-The [WhatIf](https://gking.harvard.edu/whatif) package, on which `dsmextra` depends, was removed from CRAN on 2020-03-07. Similarly, the [Zelig](https://zeligproject.org/) package (a dependency of WhatIf) was temporarily archived on 2020-03-24. As this may cause issues when first setting up `dsmextra`, a patch correction has been released under version 1.1.0 to ensure that `WhatIf` and `Zelig` are automatically pulled from Github during installation. Alternatively, both packages can be manually installed either from Github or from their respective archives (see [here](https://cran.r-project.org/web/packages/WhatIf/index.html) and [here](https://cran.r-project.org/web/packages/Zelig/index.html)).
