The code worked with old versions of R and lidR on my system, but doesn't with the new versions and functions.
running the code results in following error:
library(lidR)
so_sample_las <- readLAS("so_sample_las.laz")
tree.hulls <- lidR::delineate_crowns(so_sample_las, type="concave", attribute="treeID")
#> Error in (function (cond) :
#> error in evaluating the argument 'x' in selecting a method for function 'addAttrToGeom': Evaluation error:
#> IllegalArgumentException: Invalid number of points in LinearRing found
#> 3 - must be 0 or >= 4.
As the code seems to work on other systems, it doesn't at mine. What could be the problem?
Windows 10
R 4.1.1
