These are useful if you want to see the interim output that lineprof creates.

line_profile(code, interval = 0.01, torture = FALSE)

parse_prof(path)

`code`	code to profile.
`interval`	interval, in seconds, between profile snapshots. R's timer has a resolution of at best 1 ms, so there's no reason to make this value smaller, but if you're profiling a long running function you might want to set it to something larger.
`torture`	if `TRUE`, turns on `gctorture` which forces `gc` to run after (almost) every allocation. This is useful if you want to see exactly when memory is released. It also makes R run extremely slowly (10-100x slower than usual) so it can also be useful to simulate a smaller `interval`.
`path`	path to line profiling data
