Git page for the R-package spatioTemporalALK.
This model uses age-at-length observations to construct spatio-temporal age-at-length keys. The package is needed when constructing indices-at-age using the R-package spatioTemporalIndices.
The model is installed by
devtools::install_github("NorskRegnesentral/spatioTemporalALK")For an example on how to use the model to construct indices-at-age, see https://github.com/NorskRegnesentral/spatioTemporalIndices.
A simple example to fit the model and displaying age-at-length keys is provided here: scrip\fitALK.R.
