trunpois Truncated Poisson Distribution

DESCRIPTION

Random number generation for the truncated Poisson distribution.

USAGE

rtrunpois(n, lambda = stop("no lambda arg"), origin=0)

REQUIRED ARGUMENTS

`n`		sample size. If length(n) is larger than 1, then length(n) random values are returned.
`lambda`		vector of (positive) means. This is replicated to be the same length as the number of deviates generated.

OPTIONAL ARGUMENTS

origin Non-negative integer giving the origin of the distribution.

VALUE

Vector of length n of random deviates from the Poisson distribution with mean lambda truncated to have minimum value origin.

SIDE EFFECTS

Causes creation of the dataset .Random.seed if it does not already exist, otherwise its value is updated.

EXAMPLES
