## S3 method for class 'traps'
plot(x, border = 100, label = FALSE, offset = c(6,6), add = FALSE,
  hidetr = FALSE, detpar = list(), txtpar = list(), bg = "white",
  gridlines = TRUE, gridspace = 100, gridcol = "grey", 
  markused = FALSE, markvarying = FALSE, markvertices = FALSE,
  labelclusters = FALSE, ...)

Arguments

x

a traps object

border

width of blank margin around the outermost detectors

label

logical indicating whether a text label should appear by each detector

offset

vector displacement of label from point on x and y axes

add

logical to add detectors to an existing plot

hidetr

logical to suppress plotting of detectors

detpar

list of named graphical parameters for detectors (passed to par)

txtpar

list of named graphical parameters for labels (passed to par)

bg

background colour

gridlines

logical for plotting grid lines

gridspace

spacing of gridlines

gridcol

colour of gridlines

markused

logical to distinguish detectors used on at least one occasion

markvarying

logical to distinguish detectors whose usage varies among occasions

markvertices

logical or 0,1,2 for plotting transect or polygon points

labelclusters

logical to label clusters

...

arguments to pass to eqscplot

Details

offset may also be a scalar value for equal displacement on the x and y axes. The hidetr option is most likely to be used when plot.traps is called by plot.capthist. See par and colours for more information on setting graphical parameters. The initial values of graphical parameters are restored on exit.

Axes are not labeled. Use axis and mtext if necessary.

markvertices determines whether the vertices of each transect or polygon will be emphasised by overplotting a point symbol (detpar$pch). Value may be logical (TRUE, FALSE) or integer (0 = no points, 1 = terminal vertices only, 2 = all vertices).

labelclusters requires x to have attributes ‘clusterID’ and ‘clustertrap’.

Value

None
