Compute the Value of Quantile Function over Uniform Distribution in R Programming – qunif() Function

  • Last Updated : 03 Jul, 2020

In R programming, qunif() function gives the value of quantile function over Uniform Distribution.

Syntax:
qunif(p, min, max, lower.tail = TRUE, log.p = FALSE)

Parameters:
p: represents probabilities vector
min, max: represents lower and upper limits of the distribution
lower.tail: represents logical value. If TRUE, probabilities are P[Xx]
log.p: represents logical value. If TRUE, probabilities are given as log(p)

Example 1:




# R program to find the value of
# Quantile Function
  
# Creating a vector
x <- seq(0, 1, by = 0.2)
  
# qunif() function
qunif(x, min = 2, max = 6)

Output:

[1] 2.0 2.8 3.6 4.4 5.2 6.0

Example 2:




# Create variables
x <- seq(0, 1, by = 0.02)
y <- qunif(x, min = 1, max = 5)
  
# Output to be present as PNG file
png(file = "qunifGFG.png")
  
# Plot
plot(y, type = "o"
  
# Saving the file
dev.off()
