Shared Memory Atomic Operations R package semaphore version 1.2.0 Implements named semaphores from the 'boost' 'C++' library <https://www.boost.org/> for interprocess communication. Multiple 'R' sessions on the same host can block (with optional timeout) on a semaphore until it becomes positive, then atomically decrement it and unblock. Any session can increment the semaphore.
