plot.traps: Plot traps Object

Description

Map the locations of detectors (traps).

Usage

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

Value

None

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
frame: data defining a boundary polygon (see boundarytoSF
...: 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).

From 4.4.0, polygon detectors are shaded with detpar$col and outlined (border) with detpar$fg. Use detpar$col = NA for no shading (transparent polygons).

labelclusters requires x to have attributes `clusterID' and `clustertrap'.

A boundary polygon is plotted in black if frame is not NULL.

Examples

Run this code

 temptrap <- make.grid()
 plot (temptrap, detpar = list(pch = 16, col = "blue"), 
    label = TRUE, offset = 7)
