error: sort_index(): detected NaN

When i use shapeFit(shape = "circle", algorithm = "irls"),i get an error:
error: sort_index(): detected NaN
Error in cppCircleFit(las %>% las2xyz, method, n, conf, inliers, n_best) :
sort_index(): detected NaN
My point cloud is already normalized and segmented,the previous step only used stempoint( ) to identify the trunk points.

I have the same problem here. Did you solve?

I found the same issue, with one of my datasets. The biggest difference between this one and my others was that I used cloud compare to edit these datasets. (It was not cloud compare)

So did some very light research and found out this is due to not having enough data to compute a DBH on a given tree. This is likely never going to happen with terrestrial data but in my scan there were some areas were the a few meters above the ground were invisible. If you see this error, I will swap to another one of the algorithm options that is NAN friendly.
