This is very experimental and has not been thoroughly tested. Use with caution.
This function will reparse a single module (currently) into the simList
where its source code should reside, and then optionally restart a simulation
that stopped on an error, presumably after the developer has modified the
source code of the module that caused the break.
This will restart the simulation at the next event in the event queue
(i.e., returned by events(sim)). Because of this, this function will
not do anything if the event queue is empty.
restartSpades(sim = NULL, module = NULL, numEvents = Inf, restart = TRUE, ...)A simList. If not supplied (the default), this will take the sim from
SpaDES.core:::.pkgEnv$.sim, i.e., the one that was interrupted
A character string length one naming the module that caused the error and whose source code was fixed. This module will be reparsed and placed into the simList
Numeric. Default is Inf (i.e., all available). In the simList, if
options('spades.recoveryMode') is set to TRUE or a numeric, then
there will be a list in the simList called .recoverableObjs. These will be
replayed backwards in time to reproduce the initial state of the simList before
the event that is numEvents back from the first event in events(sim).
Logical. If TRUE, then the call to spades will be made, i.e.,
restarting the simulation. If FALSE, then it will return a new simList
with the module code parsed into the simList
Passed to spades, e.g., debug, .plotInitialTime
A simList as if spades had been called on a simList.
This will only parse the source code from the named module. It will not affect any
objects that are in the mod or sim.
The random number seed will be reset to the state it was at the start of the earliest event recovered, thereby returning to the exact stochastic simulation trajectory.
This will only work reliably
if the simList was not modified yet during the event which caused the error.
The simList will be in the state it was at the time of the error.
