A set of boolean tests on objects
Description
is.empty
tests if a LAS
object is a point cloud with 0 points.
is.overlapping
tests if a LAScatalog
has overlapping tiles.
is.indexed
tests if the points of a LAScatalog
are indexed with .lax
files.
is.algorithm
tests if an object is an algorithm of the lidR package.
is.parallelised
tests if an algorithm of the lidR package is natively parallelised with OpenMP.
Returns TRUE if the algorithm is at least partially parallelised i.e. if some portion of the code is
computed in parallel.
Usage
is.empty(las)
is.overlapping(catalog)
is.indexed(catalog)
is.algorithm(x)
is.parallelised(algorithm)
