secr (version 3.0.1)

spacing: Detector or Mask Spacing

Description

Extract or replace the spacing attribute of a detector array or mask.

Usage

spacing(object, …)
spacing(object) <- value
# S3 method for traps
spacing(object, ..., recalculate = FALSE)
# S3 method for mask
spacing(object, ..., recalculate = FALSE)

Arguments

object

object with `spacing' attribute e.g. traps

value

numeric value for spacing

…

other arguments (not used)

recalculate

logical; if TRUE compute average spacing afresh

Value

scalar numeric value of mean spacing, or a vector if object has multiple sessions

Details

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.
