How to convert integer number to string in R?

A comprehensive guide on how to convert an integer number to string in R.

Variables are used to store data in any programming language. In R language, the data type is checked at run time. The different data types in R include Character, Numeric, Integer, Factor, and Logical. There are a few instances where we need to convert one data type into another to use the information further to perform operations. This is known as data type-casting.

This guide will show you how in R, one can convert number to string (also known as character data type in a few languages).

How to convert number to string in R?

There are two simple steps in R to convert number to string- Define an integer variable and then convert to string in R. Let us understand these steps in detail and learn how to perform R numeric to string conversion.

Step 1: Define an integer variable

We use the as.integer() function to define any integer value.

a = as.integer(2)

To check the data type of a variable, we use class() function

class(a)

'Integer'

Step 2: R Int to String Conversion

We use as.character() function to convert any data type to character/string data type

b = as.character(a) b

'2'

To check the data type of a variable, we use class() function

class(b)

'character'

How to make a string to number in R?

In R, you can convert a string to a number using the as.numeric() function. This function takes a single argument, which is the string you want to convert.

Step-1 Create a String

Use this sample code to create a string in R.

my_string <- "42.5"

Step 2: R Change String to Number Conversion

my_number <- as.numeric(my_string)

Step 3: Print the result

Simply print the result to analyze the conversion of string to number in R.

print(my_number)

In this example, we start with the string "42.5" and use as.numeric() to convert it into a numeric value. The result is the number 42.5.
