Accessor functions for the outputs slots in a simList object.
If a module saves a file to disk during events, it can be useful to keep track
of the files that are saved e.g., for saveSimList() so that all files can
be added to the archive. In addition to setting outputs at the simInit
stage, a module developer can also put this in a using any saving mechanism that
is relevant (e.g., qs::qsave, saveRDS etc.). When a module event does this
it can be useful to register that saved file. registerOutputs offers an additional
mechanism to do this. See examples.
outputs(sim)
# S4 method for simList
outputs(sim)
outputs(sim) <- value
# S4 method for simList
outputs(sim) <- value
registerOutputs(filename, sim, ...)
outputArgs(sim)
# S4 method for simList
outputArgs(sim)
outputArgs(sim) <- value
# S4 method for simList
outputArgs(sim) <- valueA simList. If missing, then the function will search in the call
stack, so it will find it if it is in a SpaDES module.
The object to be stored at the slot. See Details.
The filename to register in the outputs(sim) data.frame. If
missing, an attempt will be made to search for either a file or filename
argument in the call itself. This means that this function can be used with
the pipe, as long as the returned return from the upstream pipe function is
a filename or if it is NULL (e.g., saveRDS), then it will find the file
argument and use that.
Not used.
A simList which will be the sim passed in with a new object registered
in the outputs(sim)
These functions are one of three mechanisms to add information about which output files to save.
As arguments to a simInit call. Specifically, inputs or outputs.
See ?simInit.
With the outputs(simList) function call.
By adding a function called .inputObjects inside a module, which will be executed
during the simInit call. This last way is the most "modular" way to create
default data sets for your model.
See below for more details.
Note using registerOutputs: a user can pass any other
arguments to registerOutputs that are in the
outputs(sim) data.frame, such as objectName, fun, package, though these
will not be used to save the files as this function is only about
registering an output that has already been saved.
The automatic file type handling only adds the correct extension from a given
fun and package. It does not do the inverse, from a given extension find the
correct fun and package.
simInitoutputs accepts a data.frame similar to the inputs data.frame, but
with up to 6 columns.
objectName | required, character string indicating the name of the object
in the simList that will be saved to disk (without the sim$ prefix). |
file | optional, a character string indicating the file path to save to.
The default is to concatenate objectName with the model timeunit and
saveTime, separated by underscore, '_'. So a default filename would be
"Fires_year1.rds". |
fun | optional, a character string indicating the function to use to
save that file. The default is saveRDS() |
package | optional character string indicating the package in
which to find the fun); |
saveTime | optional numeric, indicating when in simulation time the file
should be saved. The default is the lowest priority at end(sim),
i.e., at the very end. |
arguments | is a list of lists of named arguments, one list for each
fun. For example, if fun = "write.csv",
arguments = list(row.names = TRUE) will pass the argument
row.names = TRUE to write.csv If there is only one list,
then it is assumed to apply to all files and will be recycled as per normal R
rules of recycling for each fun. |
See the modules vignette for more details (browseVignettes("SpaDES.core")).
registerOutputs() which enables files that are saved to be added to
the simList using the outputs(sim) mechanism, so the files that are saved
during a module event can be tracked at the simList level. saveSimList()
which will optionally add all the outputs that are tracked into an archive.
