Compute the Value of Poisson Quantile Function in R Programming - qpois() Function Last Updated : 25 Jun, 2020 Comments Improve Suggest changes Like Article Like Report 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 Example 1: Python3 1== # 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 Output: [1] 0 1 1 1 1 2 2 2 2 2 2 2 2 3 3 3 3 3 [19] 3 3 3 3 3 3 3 3 3 4 4 4 4 4 4 4 4 4 [37] 4 4 4 4 4 4 4 4 4 5 5 5 5 5 5 5 5 5 [55] 5 5 5 5 5 5 5 5 6 6 6 6 6 6 6 6 6 6 [73] 6 6 6 6 6 7 7 7 7 7 7 7 7 7 7 8 8 8 [91] 8 8 8 8 9 9 9 10 10 11 Inf Example 2: Python3 1== # R program to compute # Poisson Quantile Density # Sequence of x-values x <- seq(0, 1, by = 0.01) # Calling qpois() Function y <- qpois(x, lambda = 15) # Plot a graph plot(y) Output: Comment More infoAdvertise with us Next Article Compute the Value of Poisson Quantile Function in R Programming - qpois() Function N nidhi_biet Follow Improve Article Tags : R Language R Statistics Similar Reads Compute value of Logistic Quantile Function in R Programming - qlogis() Function qlogis() function in R Language is used to compute the value of logistic quantile function.
