In this R Programming Tutorial, we explain everything about linear and nonlinear modelling, data analysis, and time-series analysis with great extent. It’s easy coding, wide number of packages, and Free software is making people crazy about R programming language.
R is a programming language provides a software environment for graphics, and statistical computing. R Programming provides a wide variety of graphical techniques, and in this tutorial we will explain most of them.
Introduction to R Programming Tutorial
Operators in R Programming
Decision Making & Loops
Loops are helpful to execute a fixed number of lines for number of times. R control structures allows us to control the execution flow of a series of statements or expressions. Based on the condition or input, control structures will respond by executing the expressions.
The following R programming tutorial explains the loops, and the decision making statements with practical example.
- If Statement
- If Else Statement
- Nested If Else Statement
- Else If Statement
- Switch Statement
- Break Statement
- Next Statement
- While Loop
- For Loop
- Repeat Loop
R Objects
R Programming always works with objects. The following list are the available objects in R programming to work with data.
Data Sources
- Create ODBC Connection
- Create SQL Server Native Client 11.0 Connection
- Read Data from SQL Server
- Read Data from CSV File
- Import Data From Text File using read.table
