I would like to try "lasdetectshape" in lidR package to detect line pattern objects in my point cloud.

library(lidR)
las <- readLAS("9a-1.las", select = 'xyzicnrRGB')

las <- lasdetectshape(las, shp_line, attribute = "Shape", filter = NULL)

However, getting following error:

Error in lasdetectshape(las, shp_line, attribute = "Shape", filter = NULL)   

could not find function "lasdetectshape"

I tried re-install lidR package and re-started R with no sucess.

    What version of lidR have you got? What does packageVersion("lidR") say?

The function lasdetectshape() was introduced in version 2.1.0. You are running an old version which is 8 months old. lidR is a constantly evolving package. New features are regularly added, internal improvement are regularly made (memory usage and speed usually) and many bugs are fixed. Try to run an up-to-date version of the package at stay informed of the change with the changelogs.
