library(tidyverse) library(scales) Exponential growth Exponential growth, that is something that is growing relative to its science, hence ubuiquitious in nature, is conveniently and elegantly described by the growth constant (e): [y = e^{\lambda x}] And its graph is this for (\lambda=1): p0 <- ggplot(data.frame(x = seq(from = 0, to = 3, by = .1))) + aes(x = x) + theme_minimal() p0 + stat_function(fun = ~ exp(.x)) exp(x) does nothing more than computing (e^x), where (e \approx …
