Detector or Mask Spacing
Extract or replace the spacing attribute of a detector array or mask.
spacing(object, ...) spacing(object) <- value ## S3 method for class 'traps' spacing(object, ..., recalculate = FALSE) ## S3 method for class 'mask' spacing(object, ..., recalculate = FALSE)
object |
object with ‘spacing’ attribute e.g. |
value |
numeric value for spacing |
... |
other arguments (not used) |
recalculate |
logical; if TRUE compute average spacing afresh |
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)
