Compute Randomly Drawn F Density in R Programming - rf() Function

Last Updated : 15 Jul, 2025
rf() function in R Language is used to compute random density for F Distribution.
Syntax: rf(N, df1, df2) Parameters: N: Sample Size df: Degree of Freedom
Example 1: Python3 1== 
# R Program to compute random values
# of F Density

# Setting seed for
# random number generation
set.seed(1000)

# Set sample size
N <- 20

# Calling rf() Function
y <- rf(N, df1 = 2, df2 = 3)
y
Output: 
 [1]  0.2254501 19.1565944  0.1462503  0.1443822  0.5184883  0.9231497

[19]  0.4680668 12.6245564
Example 2: Python3 1== 
# R Program to compute random values
# of F Density

# Setting seed for
# random number generation
set.seed(1000)

# Set sample size
N <- 100

# Calling rf() Function
y <- rf(N, df1 = 2, df2 = 3)

# Plot a graph
plot(y)
