The ‘spacing’ attribute of a detector array is the average distance from one detector to the nearest other detector.
The attribute was not always set by make.grid()
and
read.traps()
in versions of secr before 1.5.0. If the
attribute is found to be NULL then spacing
will compute it on the
fly.
scalar numeric value of mean spacing, or a vector if object
has multiple sessions
temptrap <- make.grid(nx = 6, ny = 8)
spacing(temptrap)
