sampled_index: Function to automate the rank trends by taxanomic group

In bcgov/ranktrends: Summarise species data based on common conservation ranking systems

Description

This function generates confidence intervals for ranks by taxanomic groups by resampling species within a given group at each time point.

Usage

sampled_index(wt_data, tax_group, wts_col, yr_col, nreps = 1000)

Arguments

wt_data	input dataframe of species weighted ranks
tax_group	name of column that contains grouping variable e.g. "taxonomic group"
wts_col	name of column with numeric weight values (e.g. "wts_col")
yr_col	name of column that specifies assessment (e.g. "year")
nreps	number of times to subsample species weights (default = 1000)

Value

a dataframe containing mean, upper and lower confidence interval for samples conservation status index
