Explain some of the useful functions provided by R which can perform vector operations.

Let us assign the following vectors

v <- c(12,45,100,2)

To perform sum of all the elements we can use sum() function which will add each of the elements present in a vector

sum(v)

[1] 159

To perform mean of all the elements we can use mean() function which will calculate the average of the vector

mean(v)

[1] 39.75

To perform variance of all the elements we can use var() function which will calculate the variance of all the elements present in a vector.

var(v)

[1] 1950.917

To perform standard deviation of all the elements we can use sd() function

sd(v)

[1] 44.16918

To perform maximum of all the elements we can use max() function

max(v)

[1] 100

To perform a minimum of all the elements we can use min() function

min(v)

[1] 2

To perform product of all the elements we can use prod() function

prod(v)

[1] 108000
