cov()
function in R Language is used to measure the covariance between two vectors.
Syntax: cov(x, y, method)
Parameters:
x, y: Data vectors
method: Type of method to be used
Example 1:
# Data vectors x < - c( 1 , 3 , 5 , 10 )
y < - c( 2 , 4 , 6 , 20 )
# Print covariance using Pearson method print (cov(x, y, method = "pearson" ))
|
Output:
[1] 30.66667
Example 2:
# Data vectors x < - c( 1 , 3 , 5 , 10 )
y < - c( 2 , 4 , 6 , 20 )
# Print covariance using Pearson method print (cov(x, y, method = "kendall" ))
|
Output:
[1] 12
Example 3:
# Data vectors x < - c( 1 , 3 , 5 , 10 )
y < - c( 2 , 4 , 6 , 20 )
# Print covariance using Pearson method print (cov(x, y, method = "spearman" ))
|
Output:
[1] 1.666667
