Find Sum, Mean and Product of a Vector in R

sum(), mean(), and prod() methods are available in R which are used to compute the specified operation over the arguments specified in the method. In case, a single vector is specified, then the operation is performed over individual elements, which is equivalent to the application of for loop. 

Function Used:

• mean() function is used to calculate mean

Syntax: mean(x, na.rm)

Parameters:

• x: Numeric Vector
• na.rm: Boolean value to ignore NA value

• sum() is used to calculate sum

Syntax: sum(x)

Parameters:

• x: Numeric Vector

• prod() is used to calculate product

Syntax: prod(x)

Parameters:

• x: Numeric Vector

Given below are examples to help you understand better.

Example 1:

Output

[1] "Sum of the vector:"

[1] 10

[1] "Mean of the vector:"

[1] 2.5

[1] "Product of the vector:"

[1] 24

Example 2:

Output

[1] "Sum of the vector:"

[1] 6.1

[1] "Mean of the vector:"

[1] 2.033333

[1] "Product of the vector:"

Example 3 : Vector with NaN values 

Output

[1] "Sum of the vector:"

[1] NA

[1] "Mean of the vector with NaN values:"

[1] NA

[1] "Mean of the vector without NaN values:"

[1] 2.033333

[1] "Product of the vector:"

[1] NA
