summary.traps: Summarise Detector Array
Description
Concise description of traps
object.Usage
## S3 method for class 'traps':
summary(object, getspacing = TRUE, \dots)
## S3 method for class 'summary.traps':
print(x, terse = FALSE, \dots)
Arguments
getspacing
logical to calculate spacing of detectors from scratch
terse
if TRUE suppress printing of usage and covariate summary
...
arguments passed to other functions
Value
- An object of class
summary.traps
, a list with elements - detector
detector
type ("single", "multi", "proximity" etc.) - ndetectornumber of detectors
- xrangerange of x coordinates
- yrangerange of y coordinates
- spacingmean distance from each trap to nearest other trap
- usagetable of usage by occasion
- covarsummary of covariates
Details
When object
includes both categorical (factor) covariates and
usage
, usage is tabulated for each level of the covariates.
Computation of spacing
(mean distance to nearest trap) is slow
and may hit a memory limit when there are many traps. In this case, turn
off the computation with getspacing
= FALSE.Examples
