I can reproduce this on Travis but not yet on my own machine. Very puzzling.

It's not finding the sample data! Passing an empty string to process_pcl produces exactly the same output CRAN got:

process_pcl("", marker.spacing = 10, user_height = 1.05,
+ max.vai = 8, pavd = FALSE, hist = FALSE)
how many in base df have NA
[1] 0
Transect Length
[1] -10
Error in `$<-.data.frame`(`*tmp*`, "sky_hit", value = TRUE) : 
  replacement has 1 row, data has 0
In addition: Warning message:
In file(file, "rt") :
  file("") only supports open = "w+" and open = "w+b": using the former
