Coerce an mrgsims object to 'Apache' 'Arrow'-backed mrgsimsds object

Converts the output of mrgsolve::mrgsim() to an mrgsimsds object by writing the simulation data to a parquet file in tempdir(). Files in tempdir() are auto-deleted on garbage collection by default. Use move_ds() or save_ds() to relocate files outside tempdir(), which automatically disables gc, or call gc_ds() to control gc directly.

Usage

as_mrgsim_ds(x, verbose = FALSE, gc = TRUE)

Arguments

x

an mrgsims object.

verbose

if TRUE, print progress information to the console.

gc

initial gc setting; if TRUE, a finalizer function will attempt to remove files once the object is out of scope. This value is not locked: move_ds() and save_ds() will automatically adjust gc based on whether the files remain under tempdir(). To lock the gc setting and prevent automatic adjustment, call gc_ds() after creation.

Value

An object with class mrgsimsds.

mod <- house_ds()

data <- ev_expand(amt = 100, ID = 1:10)

out <- mrgsolve::mrgsim(mod, data)

obj <- as_mrgsim_ds(out)
