as.mask

Coerce traps object to mask

Description

This function is used primarily for plotting covariates, for which the plot.mask function has greater functionality than plot.traps. It also generates pretty maps of grid cells.

Usage

as.mask(x)

Arguments

`x`	an object of class 'traps'

Details

A mask derived by coercion with as.mask may behave unpredictably e.g., in secr.fit.

Value

If x is a single-session traps object –

an object of class c("mask", "data.frame")

If x is a multi-session traps object –

an object of class c("mask", "list"), for which each component is a single-session mask.

Examples

plot(as.mask(traps(captdata)), dots = FALSE, meshcol = "black")
plot(traps(captdata), add = TRUE)
