Arguments

lasR_project_csv	csv file of intersections created by lasR_project() function
dir_out	where should csv files be sent
n_core	number of corest to run process on
gridmetrics_path	where is gridmetrics.exe (FUSION)
heightbreak	Height break for cover calculation
cellsize	output raster resolution
minht	set minht for gridmetrics.ex
first	T/F use only first returns
intensity	T/F include intensity metrics
outlier	c(-5,500) range of inclusion
fusion_switches	other fusion switches as a string e.g. "/noground"
xmn, xmx, ymn, ymx	set extent for analysis
