Density-dependent aggregation model
Description
dda
is a list of matrices representing results from the
density-dependent aggregation model (Siteur et al. 2023) in dda
.
dda.pars
is a data frame with the model parameters. Each row of
dda.pars
corresponds to a matrix in dda
, in the same order. All
parameters were maintained constant, except for tau (see model
definition in Siteur et al. 2023).
Usage
dda
dda.pars
Format
An object of class list
of length 4.
An object of class data.frame
with 4 rows and 5 columns.
