%description
A framework for fitting adaptive forecasting models. Provides a way to use
forecasts as input to models, e.g. weather forecasts for energy related
forecasting. The models can be fitted recursively and can easily be setup
for updating parameters when new data arrives. See the included vignettes,
the website <https://onlineforecasting.org> and the paper "onlineforecast:
An R package for adaptive and recursive forecasting"
<https://journal.r-project.org/articles/RJ-2023-031/>.
