Probability mass function for a Poisson distribution.

Source: R/poisson_dist.R

Returns a function that evaluates the Poisson PMF at given points.

# S3 method for class 'poisson_dist'
density(x, ...)

Arguments

x

A poisson_dist object.

...

Additional arguments (not used).

Value

A function function(k, log = FALSE, ...) returning the probability mass (or log-probability) at k.

Examples

x <- poisson_dist(5)
f <- density(x)
f(5)
#> [1] 0.1754674
f(0)
#> [1] 0.006737947
