About R

R is very popular for data analytics which was created by Ross Ihaka and Robert Gentleman in 1993. Many big companies like Google, Facebook, Airbnb etc uses this language for data analytics. R is good for software developers, statisticians and data miners.

Key Features

• Interpreted programming language(no compilation required)
• provides highly extensible graphical techniques.
• Good community support
• Free and open-source
• Handles data very effectively.

Data Types

Data type	Description	Usage
Numeric	To represent decimal values	x=1.84
Integer	To represent integer values, L tells to store the value as integer	x=10L
Complex	To represent complex values	x = 10+2i
Logical	To represent boolean values, true or false	x = TRUE
Character	To represent string values	x <- "One compiler"
raw	Holds raw bytes

Variables

Variables can be assigned using any of the leftward, rightward or equal to operator. You can print the variables using either print or cat functions.

Loops

1. IF Family:

If, If-else, Nested-Ifs are used when you want to perform a certain set of operations based on conditional expressions.

If

If-else

Nested-If-else

2. Switch:

Switch is used to execute one set of statement from multiple conditions.

3. For:

For loop is used to iterate a set of statements based on a condition.

4. While:

While is also used to iterate a set of statements based on a condition. Usually while is preferred when number of iterations are not known in advance.

5. Repeat:

Repeat is used tyo iterate a set of statements with out any condition. You can write a user-defined condition to exit from the loop using IF.

Functions

Function is a sub-routine which contains set of statements. Usually functions are written when multiple calls are required to same set of statements which increases re-usuability and modularity.

Vectors

Vector is a basic data strucre where sequence of data values share same data type.

For example, the below statement assigns 1 to 10 values to x.
You can also use se() function to create vectors.

the above statement prints the output as [1] 1 3 5 7 9.
