NoSleepR exposes a tiny, cross-platform API that temporarily disables system
sleep while your R script performs a long-running operation. The package
delegates to the native inhibition mechanisms shipped with each platform
(Win32 power requests, caffeinate, or systemd-inhibit) and automatically
tears them down once you are done.
Call nosleep_on() (optionally with keep_display = TRUE) right
before a long computation or data transfer.
Run the expensive task.
Explicitly stop the request with nosleep_off() as soon as the work
finishes, or rely on with_nosleep() to bracket the code block.
NoSleepR automatically cleans up pending requests when the R session ends,
but it is still best practice to explicitly call nosleep_off() so that the
operating system can resume managing power immediately after the protected
job completes.

Core helpers
nosleep_on() — establish a sleep-prevention request and keep the
handle alive for as long as the work runs.
nosleep_off() — release a specific handle or clear all active
ones when called without arguments.
with_nosleep() — wrap a code block so that NoSleepR turns itself
on before the block executes and reliably shuts down after it completes
or errors.
All helpers accept the optional keep_display flag, allowing you to request
that the monitor stays on (when supported by the OS) in addition to the
system-wide sleep prevention.
