Usage

norm2pois(x, lambda, mu = mean(x), sd = stats::sd(x))

Arguments

x

the normally distributed vector

lambda

the mean of the distribution to return

mu

the mean of x (calculated from x if not given)

sd

the SD of x (calculated from x if not given)

Value

a vector with a poisson distribution

Examples

x <- rnorm(10000)
y <- norm2pois(x, 2)
g <- ggplot2::ggplot() + ggplot2::geom_point(ggplot2::aes(x, y))
ggExtra::ggMarginal(g, type = "histogram")
