Calculate a design index

Calculate a design-based index with bootstrapped standard errors

Usage

get_design_index(species, ssid = NULL, reps = 1000, data = NULL)

Arguments

species

Species common name or number

ssid

Survey series ID

reps

Number of bootstrap samples. Set to 0 to skip the bootstrapping and only report design-based variance estimates.

data

Optional output from a call to get_all_survey_sets(). By default, this function will call get_all_survey_sets() for the given species, but this requires access to the GFBio database, and will also be slower if you've already cached the data.
