Compute Randomly Drawn Poisson Density in R Programming – rpois() Function Last Updated : 25 Jun, 2020 Improve Improve Like Article Like Save Share Report rpois() function in R Language is used to compute random density for poisson distribution. Syntax: rpois(N, lambda) Parameters: N: Sample Size lambda: Average number of events per interval Example 1: # R program to compute random # Poisson Density # Setting seed for # random number generation set.seed(1000) # Set sample size N <- 20 # Calling rpois() Function y <- rpois(N, lambda = 5) y Output: [1] 4 6 2 6 5 2 6 5 3 3 4 6 4 7 7 2 5 6 2 5 Example 2: # R program to compute random # Poisson Density # Setting seed for # random number generation set.seed(1000) # Set sample size N <- 100 # Calling rpois() Function y <- rpois(N, lambda = 15) # Plot a graph plot(y) Output: Like Article Suggest improvement Next Compute Randomly Drawn Logistic Density in R Programming - rlogis() Function Share your thoughts in the comments Add Your Comment Please Login to comment...
