  • Last Updated : 19 Jun, 2020

rt() function in R Language is used to create a random sequence of values from Student t-distribution.

Syntax: rt(n, df, ncp)

Parameters:
n: Number of observations
df: Degree of Freedom
ncp: Numeric vector of non-centrality parameters.

Example 1:




# R Program to create random sequence
# from t distribution
  
# Calling rt() Function
rt(15, 2)
rt(15, 1)

Output:

 [1]  2.09851925 -1.76883434 -0.56019367  0.23263458  1.02778818 -0.82274015

Example 2:




# R Program to create random sequence
# from t distribution
  
# Calling rt() Function
rt(5, 1, 1:5 * 5)
rt(5, 2, 1:10)

Output:

[1] 23.88663 20.26813 62.95437 14.59003 20.58296
