# RStudio Tutorial – A Complete Guide for Novice Learners!

RStudio is one of the most popular IDE for working with the R programming language. Here in this RStudio tutorial, we’re going to cover every aspect of RStudio so that you can have its thorough understanding.

In this RStudio tutorial, we are going to perform the following operations:

- Downloading/Importing Data in R.

- Data Transformation and other Miscellaneous Data Operations.

- Performing Statistical Modeling on the Data.

- Creating Graphical Plots of Data.

## What is RStudio?

*RStudio is an open-source integrated development environment that facilitates statistical modeling as well as graphical capabilities for R. It makes use of the QT framework for its GUI features.*

There are two versions of RStudio – **RStudio Desktop** and **RStudio Server**.

*RStudio desktop provides facilities for working on the local desktop environment, whereas RStudio Server provides access through a web browser.*

**You should be aware of the Statistical Programming in R**

### Basic Data Analysis through RStudio

We will perform data analysis using RStudio in this section. We will also perform data transformation as well as graphical plotting of the resulting data distribution.

### How to Import Data in RStudio?

In order to deploy our model in RStudio, we will make use of the **ACS (American Community Survey)** dataset. We can import this data through the following command that is typed in the console window.

> ACS_data <- read.csv(url("http://stat511.cwick.co.nz/homeworks/acs_or.csv"))

**Are you aware of the Process of Importing Data in R? If not, then you should definitely learn it.**

### How to Transform Data through RStudio?

After you have imported data into your variable in RStudio, you can now apply various transformations to manipulate the data. Some techniques for accessing the data are as follows.

In order to access the **label age_husband**, we use the following command:

> greater <- subset(ACS_data , age_husband > age_wife) #Author DataFlair > head(greater)

**Output:**

In the above code, we use the function **‘subset’** and within this function, we specify our data upon which the **greater than** operation is to be applied. The second parameter performs this condition. Finally, we display the first 6 values that return the values for which **age_husband** is greater than **age_wife**.

We can perform various statistical operations as follows:

> mean(ACS_data$age_husband) #For calculating mean of column > median(ACS_data$age_husband) #For calculating median of column > quantile(ACS_data$age_wife) #For calculating the Quantile > var(ACS_data$age_wife) #For measuring the variance > sd(ACS_data$age_wife) #For calculating the Standard Deviance > #DataFlair

**Output:**

For retrieving a summary of the dataset, we use the **summary()** function:

> summary(ACS_data) #Author DataFlair

RStudio provides advanced graphics visualization features. We can plot our above data with the column label **‘age_husband’** on the x-axis and column **age_wife** on the y-axis.

A scatterplot is plotted in the following manner:

In order to delineate a histogram, we make use of the following command:

> get_table <- table(ACS_data$bedrooms) > barplot(get_table, main="Bedrooms Distribution", xlab="Bedroom Count") #Author DataFlair

**Output:**

## Summary

In this RStudio tutorial, we learned about the basics of RStudio. We inferred how to import data, transform it, perform analysis on the data and finally, visualize the data. We hope that you understood all the processes of RStudio with this article.

**Now, the next concept is going to be an interesting one, that is – R Data Structures**
