conv_thresholds {telemetR}R Documentation

Calculate Convergence Thresholds for the rSSR curve

Description

Takes a dataframe created by renorm_SSR and calculates the range in values and then calculates thresholds given. Suggested values are 0.5, 0.1, and 0.005. The rSSR calculated for each MBP should decrease with each increasing blanking period until they reach close to zero, which We consider convergence. Since the rSSR curve generally bounces around an assymptote and often does not reach or stay at 0, we set a threshold a priori for identifying convergence.

Usage

conv_thresholds(rSSR_df, var_groups, thresh_levels = c(0.05, 0.01, 0.005))

Arguments

rSSR_df

a dataframe created by created by renorm_SSRduration compare showing the renormalized sum of squares of the residuals between one potential blanking period and the next.

var_groups

a single string or vector of strings of the columns which should be used to group organisms. Common groupings are species and cohorts.

thresh_levels

a single value or vector of values used to set thresholds for identifying convergence.

Value

A dataframe of rSSR values corresponding to the given convergence threshold

Examples

# Calculate the 95% "convergence" threshold for the rSSR data
conv_thresholds(rSSR_df = ex_rSSR,
                var_groups = "fish_type",
                thresh_levels = 0.05)
