Data Manipulation With Dplyr in R

📘 Course Overview:

🎉 Data Manipulation With Dplyr in R - A Straightforward Tutorial in Data Wrangling with one of the most powerful R packages - dplyr! 🚀

Why Learn dplyr?

Data manipulation is the bedrock of data analysis, and as a data analyst, you'll spend a significant portion of your time preparing or processing data. The dplyr package in R is designed to streamline this process, offering a suite of tools that make data preparation more efficient, faster, and easier to understand.

🌟 Key Advantages of Using dplyr:

• Performance: dplyr operates at least 25-30 times faster than base R operations.
• Readability: Its syntax is clear and concise, making it a breeze to write and understand.
• Chaining: This feature allows you to perform multiple tasks in a single sequence of commands, enhancing both speed and readability.

Given these advantages, it's no wonder dplyr has become the preferred choice among R data scientists for data manipulation tasks.

What You Will Learn:

This course is designed to be succinct yet comprehensive, focusing on the most essential commands and functions within dplyr that you will use frequently in your work. Here's a sneak peek at what you'll learn:

1. Core Commands of dplyr:

   • filter: Subset data frames based on criteria.
   • select: Choose specific variables for analysis.
   • mutate: Compute new variables or modify existing ones.
   • arrange: Sort your data frames.
   • summarise: Calculate summary statistics.

   With examples like filtering male subjects with an income above $30,000, computing income per family member, removing unnecessary variables, sorting employees by salary, and averaging customer satisfaction, you'll see how versatile these commands are in real-life scenarios.

2. Additional dplyr Commands and Functions:

   • Count observations within groups.
   • Extract random samples from data frames.
   • Retrieve top entries based on variables.
   • Visualize data set structures.
   • Perform set operations with enhanced capabilities.

3. Chaining: Learn how to perform multiple tasks in a single command, saving you time and effort.

4. Joining Data Frames: Master the five join types available in dplyr: inner_join, semi_join, left_join, anti_join, and full_join. Understand the output of each through clear examples.

5. Combining dplyr with ggplot2: Harness the full power of R by combining data manipulation with visualization, creating compelling charts and graphs for your analyses.

Learning Experience:

Each command is demonstrated with video, ensuring you understand both the syntax and the resulting output. The course culminates in a series of practical exercises designed to reinforce what you've learned and allow you to apply your new skills to real-world data sets.
