Section 51 Poisson Distribution: R function

Density, distribution function, quantile function and random generation for the Poisson distribution with parameter lambda.

?dpois

51.1 Density

dpois(x, lambda, log = FALSE)

51.2 Distribution function

ppois(q, lambda, lower.tail = TRUE, log.p = FALSE)

51.3 Quantile function

qpois(p, lambda, lower.tail = TRUE, log.p = FALSE)

51.4 Random Poisson sample

rpois(n, lambda)

51.5 Arguments

x : vector of (non-negative integer) quantiles.

q : vector of quantiles.

p : vector of probabilities.

n : number of random values to return.

lambda : number of random values to return.

log, log.p : logical; if TRUE, probabilities p are given as log(p).

lower.tail : logical; if TRUE (default), probabilities are P[X ≤ x], otherwise, P[X > x].
