R/simList-accessors.R
objects.RdThe [[ 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(sim, ...)
# S4 method for class 'simList'
objs(sim, ...)
objs(sim) <- value
# S4 method for class 'simList'
objs(sim) <- value
moduleObjects(sim, module, path)
findObjects(objects, sim, module, path)A simList object from which to extract element(s) or in which to replace element(s).
passed to ls
objects to assign to the simList
Character vector of module name(s)
The path to the module., i.e., the modulePath.
Only relevant if sim not supplied.
A character vector of length >= 1 with name(s) of objects to look
for in the metadata. This is used in a grep, meaning it will do partial
matching (e.g., "studyArea" will find "studyArea" and "studyAreaLarge").
User can use regular expressions.
Returns or sets a list of objects in the simList environment.
moduleObjects returns a data.table with 4 columns, module, objectName, type, and desc,
pulled directly from the object metadata in the createsOutputs and expectsInputs. These
will be determined either from a simList or from the module source code.
findObjects returns a data.table similar to moduleObjects, but with only the
objects provided by objects.
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 environment.
