percap_growth {gauseR}

Per-capita growth rate

Description

Calculates per-capita growth rate, using log ratios following the formula dN/Ndt = log(N(t)/N0)/dt.

Usage

percap_growth(x, laggedx, dt)

Arguments

x

Abundance

laggedx

Lagged abundance

dt

Time lag between observations

Value

Per-capita growth rate

Examples

data(gause_1934_science_f02_03)
lagged_data <- get_lag(x=gause_1934_science_f02_03$Volume_Species1,
               time = gause_1934_science_f02_03$Day,
               treatment = gause_1934_science_f02_03$Treatment)
dNNdt <- percap_growth(x=lagged_data$x, laggedx=lagged_data$laggedx,
               dt=lagged_data$dt)
