redefined_behaviors

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 replacement method for signature 'LAS'
x$name <- value

## S4 replacement method for signature 'LAS,ANY,missing'
x[[i, j]] <- value

## S4 method for signature 'LAS,numeric,ANY'
x[i]

## S4 method for signature 'LAScatalog,ANY,ANY'
x[i, j, ..., drop = TRUE]

## S4 replacement method for signature 'LAScatalog,ANY,ANY'
x[[i, j]] <- value

## S4 replacement method for signature 'LAScatalog'
x$name <- value

Arguments

`x`	A `LAS*` object
`name`	A literal character string or a name (possibly backtick quoted).
`value`	typically an array-like R object of a similar class as x.
`i`	string, name of elements to extract or replace.
`j`	Unused.
`...`	Unused
`drop`	Unused

Examples

## Not run: 
LASfile <- system.file("extdata", "Megaplot.laz", package="lidR")
las = readLAS(LASfile)

las$Z = 2L
las[["Z"]] = 1:10
las$NewCol = 0
las[["NewCol"]] = 0

## End(Not run)
