Compute the Value of Poisson Quantile Function in R Programming – qpois() Function
  • Last Updated : 25 Jun, 2020

qpois() function in R Language is used to compute the value of Poisson Quantile Function. It creates a quantile density plot for poisson distribution.

Syntax: qpois(vec, lambda)

Parameters:
vec: Sequence of integer values
lambda: Average number of events per interval

# R program to compute 
# Poisson Quantile Density
  
# Sequence of x-values
x <- seq(0, 1, by = .01)
  
# Calling qpois() Function
y <- qpois(x, lambda = 5)
y
