Observation detection tables

Description

Plot the tables created by det.tables. Produces a series of tables for dual observer data that shows the number missed and detected for each observer within defined distance classes.

Usage

## S3 method for class 'det.tables'
plot(
  x,
  which = 1:6,
  angle = NULL,
  density = NULL,
  col1 = "white",
  col2 = "lightgrey",
  new = TRUE,
  ...
)

Arguments

x

object returned by det.tables

which

items in x to plot (vector with values in 1:6)

angle

shading angle for hatching

density

shading density for hatching

col1

plotting colour for total histogram bars.

col2

plotting colour for subset histogram bars.

new

if TRUE new plotting window for each plot

...

other graphical parameters, passed to plotting functions

Details

Plots that are produced are as follows (controlled by the which argument):

1

Detected by either observer/Detected by observer 1

2

Detected by either observer/Detected by observer 2

3

Seen by both observers

4

Seen by either observer

5

Detected by observer 2/Detected by observer 1 | 2

6

Detected by observer 1/Detected by observer 2 | 1

Value

Just plots.
