There are number of uses for ...
which depend on the function
used for them. These are described below.
Most of these return named lists where names correspond to
ipm_ids
. The exception is pdb_new_fun_form
, which returns a list
of expressions. It is only intended for setting new expressions with
vital_rate_exprs<-
.
pdb_new_fun_form
This must be used when setting new expressions for
vital rates and kernel formulae. The ...
argument should be a named list
of named lists. The top most layer should be ipm_id
's. The next layer
should be a list where the names are vital rates you wish to modify, and the
values are the expressions you want to insert. See examples.
make_iter_kernel
The ...
here should be expressions representing the block kernel of
the IPMs in question. The names of each expression should be the ipm_id,
and the expressions should take the form of c(<upper_left>,
<upper_right>, <lower_left>, <lower_right>)
(i.e. a vector of symbols would create a matrix in row-major order).
See examples.
conv_plot
/lambda
The ...
are used pass additional arguments to lambda
and conv_plot
.
