set_lidr_threads: Set or get number of threads that lidR should use

In lidR: Airborne LiDAR Data Manipulation and Visualization for Forestry Applications

Set or get number of threads that lidR should use

Description

Set and get number of threads to be used in lidR functions that are parallelized with OpenMP. 0 means to utilize all CPU available. get_lidr_threads() returns the number of threads that will be used. This affects lidR package but also the data.table package by internally calling setDTthreads because several functions of lidR rely on data.table but it does not change R itself or other packages using OpenMP.

Usage

set_lidr_threads(threads)

get_lidr_threads()

Arguments

threads

Positive scalar. Default 0 means use all CPU available. Values > 1 mean using n cores, values in ]0, 1[ mean using a fraction of the cores e.g. 0.5 = half.
