Transform CRS LiDAR point clouds in lidR

Question

Is there a way to change the projection (like st_transform from sf package) of LiDAR point cloud while remaining in R?

With lidR package you can set but not modify the point cloud projection. I know las2las from lastools could do the job (and this part is open) but I would like to keep it simple, within R and without hard copying the input/output of this process.

Any advice?

This question has already been answered on gis.stackexchange. In short you can use spTransform on a LAS object but it is recommended to used las2las

library(lidR)
LASfile <- system.file("extdata", "Megaplot.laz", package="lidR")
las <- readLAS(LASfile)
las2 <- spTransform(las, sp::CRS(SRS_string = "EPSG:26918"))
