6 Great R Packages Every Beginners Should Know

Getting started with data science? The R language is your companion, offering a plethora of functionalities for statistical computing, data analysis, and visualization. Dive into our beginner-friendly tutorial on R and discover six key packages that enhance your data science journey.

Why Choose R for Data Science?

R has established its position as a top choice for data scientists. Not only is it open-source, but it also provides a comprehensive environment for data analysis and graphics.

How to Set Up R for Maximum Efficiency

Before delving into the intricacies of R, it's pivotal to have the right setup:

1. R Installation

Visit CRAN (Comprehensive R Archive Network) (opens in a new tab) and ensure you're working with the latest R version.

2. RStudio: Your Friendly IDE

RStudio isn't just an integrated development environment; it's a gateway to efficient R programming. Get the free desktop version from RStudio's official website (opens in a new tab).

The Cornerstone: Basics of R Programming

To wield R's power, get a grip on its foundational aspects:

  • Variable Assignment: With <-, variable declaration becomes intuitive.

    x <- 5

  • Function Calls: Invoke a function with its name followed by ().

    print(x)

  • Grasping Data Structures: Know your vectors, matrices, data frames, and lists. They're the backbone of data handling in R.

Top 6 R Packages Every Data Scientist Should Know

To supercharge your R capabilities, embrace these packages:

1. dplyr: Mastering Data Manipulation

From filtering data rows to modifying variables, dplyr is your toolkit. Familiarize yourself with functions like filter(), select(), and mutate().

install.packages("dplyr")
library(dplyr)

2. ggplot2: Elevate Your Data Visualization Game

With ggplot2, your data doesn't just speak; it sings! Understand the aes() function and learn to layer your plots for richer visualizations.

install.packages("ggplot2")
library(ggplot2)

3. GWalkR (opens in a new tab): Turn Your Data into Interactive Visualization App

GWalkR (opens in a new tab) is an interactive Exploratory Data Analysis (EDA) Tool in R build by Kanaries (opens in a new tab). It integrates the htmlwidgets with Graphic Walker. It can simplify your R data analysis and data visualization workflow, by turning your data frame into a tableau-alternative User Interface for visual exploration.

install.packages("GWalkR")
library(GWalkR)

4. tidyr (opens in a new tab): The Art of Data Tidying

tidyr ensures your data is neat and accessible. Explore spread(), gather(), and more to structure your data perfectly.

install.packages("tidyr")
library(tidyr)

5. readr: Streamline Data Input and Output

Whether you're reading a CSV or outputting data, readr simplifies it all. Dive into functions like read_csv() and write_csv().

install.packages("readr")
library(readr)

6. caret: Machine Learning Simplified

For model training and machine learning in R, caret is indispensable. Train models, make predictions, and evaluate performance seamlessly.

install.packages("caret")
library(caret)

In Conclusion: The R-evolution in Data Science

Embarking on the R journey unlocks a world of data science possibilities. While the packages mentioned are fundamental, the R ecosystem offers a myriad more, each with unique capabilities. Remember, in data science, understanding your data is paramount. As you advance in R, always align your tools and methods with the data's voice.
