Calling init with the model object as the first argument
will return the model initial conditions as a numericlist
object. See numericlist for methods to deal with
cmt_list objects.
Usage
init(.x, ...)
# S4 method for mrgmod
init(.x, .y = list(), ..., .pat = "*")
# S4 method for mrgsims
init(.x, ...)
# S4 method for missing
init(.x, ...)
# S4 method for list
init(.x, ...)
# S4 method for ANY
init(.x, ...)Arguments
- .x
the model object
- ...
passed along
- .y
list to be merged into parameter list
- .pat
a regular expression (character) to be applied as a filter when printing compartments to the screen
Value
an object of class cmt_list (see
numericlist)
Details
Can be used to either get a compartment list object from a
mrgmod model object or to update the compartment initial
conditions in a model object. For both uses, the return value
is a cmt_list object. For the former use, init
is usually called to print the compartment initial conditions
to the screen, but the cmt_list object can also be coerced
to a list or numeric R object.
Examples
## example("init")
mod <- mrgsolve::house()
init(mod)
#>
#> Model initial conditions (N=3):
#> name value . name value
#> CENT (2) 0 | RESP (3) 50
#> GUT (1) 0 | . ... .
init(mod, .pat="^C") ## may be useful for large models
#>
#> Model initial conditions (N=3):
#> name value . name value
#> CENT (2) 0 | . ... .
class(init(mod))
#> [1] "cmt_list"
#> attr(,"package")
