hc05: Calculate HC05

In leppott/InvertExtirp: Extirpation Analysis for Benthic Macroinvertebrates and Fish

Description

The HC05 is calculated on each specified column of a specified data frame.

Usage

hc05(df_data, col_XC95)

Arguments

df_data	Data frame of taxa data with XC95 values in one or more columns.
col_XC95	Column names for XC95 values to calculate the HC05.

Details

The HC05 is the 5th percentile hazardous concentration of a set of related 95th percentile extirpation concentration values (XC95). The HC05 is the estimated value of the stressor at which 5

Value

A vector of values with names corresponding to the provided column names.

Examples

#' \dontrun{
# Calculate XC95 values using fish.wt.cdf example
# data
data(dta.do)
data(ss.sites)
# run function (~20 seconds)
df_tv_do <- fish.wt.cdf(datafile = dta.do, ss = ss.sites, plot = T, dogam = T
