show.detfn: Plotting a detection function.

In admbsecr: SECR models with supplementary location information

Description

Plots an estimated detection function from a model fit generated by admbsecr.

Usage

show.detfn(fit, xlim = NULL, ylim = c(0, 1), main = NULL,
  xlab = "Distance (m)", ylab = "Detection probability", add = FALSE, ...)

Arguments

xlim	A vector with two elements, giving the x-axis limits. If NULL, this is set to the buffer of the mask.
ylim	A vector with two elements, giving the y-axis limits.
add	Logical, if TRUE, the estimated detection function is added to an existing plot.
...	Further arguments to be passed to lines.
fit	A fitted model from admbsecr.
main	The main title (on top) using font and size (character expansion) par("font.main") and color par("col.main").
xlab	X axis label using font and character expansion par("font.lab") and color par("col.lab").
ylab	Y axis label, same font attributes as xlab.

Examples

## Comparison of two detection functions fitted to the same data
show.detfn(example$fits$simple.hn, main = "Detection function comparison")
show.detfn(example$fits$simple.hr, add = TRUE, col = "blue")
legend("topright", legend = c("Half normal", "Hazard rate"), lty = 1, col = c("black", "blue"), bg = "white")
