Remove isolated points from a LAS point cloud based on their neighborhood distances.

1	nnFilter(las, d = 0.05, n = 2)

`las`	`LAS` object.
`d`	`numeric` - search radius.
`n`	`numeric` - number of neighbors within `d` distance a point must have to be kept in the output.

LAS object.

file = system.file("extdata", "spruce.laz", package="TreeLS")
tls = readTLS(file)
nrow(tls@data)

nn_tls = nnFilter(tls, 0.05, 3)
