Calculate Square in R
Square in R, In this tutorial, will describe how to calculate the values of a data points to the power of two in R.
We are going to cover the following cases,
1) Square of a single value in R
2) Square of Vector in R
3) Square of the data frame in R

Example 1:- Single Value Square in R
Square of Single Value, Let’s store the value in x.
x <- 10 x [1] 10
Now we stored value 10 in x, let’s calculate the power of x using the ^ symbol
x^2 [1] 100
In another way, can calculate based on the * symbol
x**2 [1] 100
or
x*x [1] 100
Example 2:-
Square of a vector, Let’s create a vector and calculate a square of two.
vec <- 1:3 vec [1] 1 2 3
Now, based on the ^ symbol we can calculate the square, Let’s see
vec^2 [1] 1 4 9
Now we can try based on the * symbol

Instead of the ^ symbol, insert the * symbol
vec * vec [1] 1 4 9
In another case, simply put
vec**2 [1] 1 4 9
Example 3:-
Square of a data frame, Let’s create a numerical data frame for square calculation
data <- data.frame(x1 = 1:3, x2 = 2:4, x3 = 2) data
x1 x2 x3 1 1 2 2 2 2 3 2 3 3 4 2
We can apply the same code ^ symbol for square calculation.

data^2
x1 x2 x3 1 1 4 4 2 4 9 4 3 9 16 4
Let’s calculate based on * symbol
data**2
x1 x2 x3 1 1 4 4 2 4 9 4 3 9 16 4
or
data*data
x1 x2 x3 1 1 4 4 2 4 9 4 3 9 16 4
Let’s try sapply function for square calculation.
sapply(data, function(x) x^2)
x1 x2 x3 [1,] 1 4 4 [2,] 4 9 4 [3,] 9 16 4
Look’s fine, Let me know if you are using any other function for the square calculation.
