## Overview
**R** is a programming language used for statistical analysis, graphical presentation, and reporting. It also helps with data cleaning, analysis, and visualization.

## Number output in R

In R, we type the number without a quote to return a number as an output.


## Example


# to print 5
5
# to print 2.5
2.5
# to print -20
-20
# to print some other numbers
10
-1.5


## Text output in R

In R, we use single or double quotes to return a text as an output.

## Example


## Calculations in R

To perform calculations in R, we type the numbers together with the mathematical operator sign.

## Example
 

# Addition 
10 + 5

# Subtraction
10 - 5

# Multiplication
10 * 5

# Division
10 / 5 

# Modulo
10 %% 5

# Exponentiation
10 ^ 5


#     
## Print in R
R does not require the `print` function to return an output of a code. It has the ``print()`` function if we wish to use it. We use the `print()` function only when we're working with `for` loops.

## Example


"Hello world"
'Hello World'
print('Hello World')

# using a for loop
for (x in 1:5) {
  print(x)
}

> **Note:** Using the ``print()`` function is only compulsory with ``for`` loop. This is because the code is inside curly braces ``{}``.

Introduction to syntax in R

R handles statistical analysis, data cleaning, visualization, and report generation. It uses numbers without quotes and text with quotes, supports direct calculations, and has an optional print() function, essential in loops.
