Usage

library(CaribouBC)

## Predefined settings
(s1 <- caribou_settings("mat.pen"))
(s2 <- caribou_settings("pred.excl"))

## Modifying predefined settings
caribou_settings("mat.pen", c.surv.capt=0.65, pen.cap=30)

## Forecast based on settings for 75% females penned
f1 <- caribou_forecast(s1, fpen.prop = 0.75)
f2 <- caribou_forecast(s2, fpen.prop = 0.75)

## Most important results summarized
summary(f1)
summary(f2)

## Plot the results
plot(f2)
lines(f1, col = 2)
legend("topleft", col = c(1,1,2), lty = c(2,1,1),
    legend = c("No pen", "Mat pen", "Pred excl"))

## Find 'breakeven' proportion of females penned where lambda=1
(b1 <- caribou_breakeven(f1, lambda = 1))
(b2 <- caribou_breakeven(f2, lambda = 1))
f3 <- caribou_forecast(s1, fpen.prop = b1)
f4 <- caribou_forecast(s2, fpen.prop = b2)
## See that lines are truly flat
op <- par(mfrow = c(1, 2))
plot(f3, main = "Mat pen")
plot(f4, main = "Pred excl")
par(op)

## Forecast using number of penned females
## - it can be an initial number
## - or a vector of individuals for subsequent years
caribou_forecast(s1, fpen.inds = 5)
caribou_forecast(s2, fpen.inds = c(5, 0, 4, 6))
