spacing: Detector or Mask Spacing

In secr: Spatially Explicit Capture-Recapture

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 class 'traps'
spacing(object, ..., recalculate = FALSE)
## S3 method for class '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

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.

Value

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

Examples

temptrap <- make.grid(nx = 6, ny = 8)
spacing(temptrap)
