plot.popn {secr}

R Documentation

Plot Population Object

Description

Display animal locations from a popn object.

Usage

## S3 method for class 'popn'
plot(x, add = FALSE, frame = TRUE,  
    circles = NULL, collapse = FALSE, seqcol = NULL, ...)

Arguments

x	object of class popn
add	logical to add points to an existing plot
frame	logical to add frame or polygon within which points were simulated
circles	vector giving the radii if circles are to be plotted
collapse	logical; if TRUE then multiple sessions are overlaid
seqcol	color used for first detection when collapse = TRUE (optional)
...	arguments passed to eqscplot and points or symbols

Details

If circles is provided then a circle of the given radius is plotted for each animal using the symbols function. The arguments fg and bg may be used to control the colour of the perimeter and the fill of each circle (see Examples).

For a multi-session popn with turnover, collapse = TRUE allows successive locations to be joined with (type = 'o' or type = 'l').

seqcol may be a single color, a vector of colours (one per session), or a vector of two colours, one for the first and one for all later sessions in which each animal was detected.

If ... includes 'col' then 'collapse' must be specified to avoid confusion, even for single-session data (see Examples).

Examples

temppopn <- sim.popn(D = 5, expand.grid(
    x = c(0,100), y = c(0,100)))
# specify collapse to avoid partial match of col    
plot(temppopn, pch = 16, collapse = FALSE, col = "blue")

plot(temppopn, circles = 20, bg = "tan", fg = "white")
plot(temppopn, pch = 16, cex = 0.5, add = TRUE)
