R package to read and write `.las` and `.laz` binary files used to store LiDAR data.

This package is used by the [`lidR`](https://github.com/r-lidar/lidR) package and is not intended to be used by regular users. Everything you need is in the `lidR` package with a high-level front end. Only package developers who would like to build something new from a low-level API might be interested in `rlas`.

`rlas` relies on a modified version of `LASlib` and `LASzip` that were modified to be compatible with `R`. The library can therefore be compiled into `R` without any complaints from `R CMD check`. It enables R users to read and write binary files commonly used to store LiDAR data. LAS/LAZ version 1.0 to 1.4 are supported.

```r

library(rlas)

lasdata   <- read.las("")

lasheader <- read.lasheader("")

```
