Basic Mathematical Operations in R Programming

This post is gonna be pretty simple and deals with the basic mathematical operations in R programming before we go into other concepts. Some of the built-in functions are highly helpful as you move along. The four basic mathematical operations which are addition, subtraction, multiplication and division are pretty straightforward in R and easier to understand.

a <- 2+3
a

b <- 5-4
b

c <- 4*5
c

d <- 10/4
d

We will also get the output as expected:

Next is the exponential which can be done by using '^' symbol (for example: 2^4 which is equal to 16). Another is the modulus operator. In R double percentage sign is used to perform modulus operation (for example: 14%%5 which gives us result as 4).

Down here we will take a look at some built-in R functions used for mathematical purposes.

e <- 2^4
e

f <- 14%%5
f

sqrt(81)

abs(-21)

g <- 20/3
g
round(g, digits=2)

The sqrt() function calculates the square root of a number. The abs() function returns the absolute value of a number. The round() function returns the rounded value of a number. Parameters digits is used to specify the number of decimal points that you want your number to be rounded off.

The output is as follows:

Likewise there are many built-in math's functions like finding trigonometrical values, logarithmic values, generating and searching a pattern in number and so on in R.
