$<-,LAS-method: Inherited but modified methods from sp

Description

LAS* objects are Spatial objects so they inherit several methods from sp. However, some have modified behaviors to prevent some irrelevant modifications. Indeed, a LAS* object cannot contain anything, as the content is restricted by the LAS specifications. If a user attempts to use one of these functions inappropriately an informative error will be thrown.

Usage

# S4 method for LAS
$(x, name) <- value
# S4 method for LAS,ANY,missing
[[(x, i, j) <- value
# S4 method for LAS,numeric,ANY
[(x, i)
# S4 method for LAScatalog,ANY,ANY
[(x, i, j, ..., drop = TRUE)
# S4 method for LAScatalog,ANY,ANY
[[(x, i, j) <- value
# S4 method for LAScatalog
$(x, name) <- value
