Examples

# Load example sparrow data (line transect survey type)
data(sparrowDf)

# Fit half-normal detection function
dfunc <- sparrowDf |> dfuncEstim(formula=dist~groupsize(groupsize))

# Estimate abundance given a detection function
fit <- abundEstim(object = dfunc
                , area = units::set_units(4105, "km^2")
                , ci = NULL)
print(fit)
summary(fit)

## Not run: 
# Bootstrap confidence intervals (500 iterations)
# Requires ~4 min
fit <- abundEstim(object = dfunc
                , area = units::set_units(4105, "km^2")
                , ci = 0.95
                , plot.bs = TRUE
                , showProgress = TRUE)
print(fit)
summary(fit)
