The [[ and $ operators provide "shortcuts" for accessing
objects in the simulation environment.
I.e., instead of using envir(sim)$object or envir(sim)[["object"]],
one can simply use sim$object or sim[["object"]].
objs(x, ...)# S4 method for simList
objs(x, ...)
objs(x) <- value
# S4 method for simList
objs(x) <- value
# S4 method for simList,ANY,ANY
[[(x, i, j, ..., drop)
# S4 method for simList,ANY,ANY,ANY
[[(x, i) <- value
# S4 method for simList
$(x, name)
# S4 method for simList
$(x, name) <- value
A simList object from which to extract element(s) or
in which to replace element(s).
see i.
Any R object.
Indices specifying elements to extract or replace.
see i.
not implemented.
A literal character string or a name.
Returns or sets a list of objects in the simList environment.
objs can take ... arguments passed to ls,
allowing, e.g. all.names=TRUE
objs<- requires takes a named list of values to be assigned in
the simulation envirment.
