R Programming – Example 3 demonstrates how to add columns and merge data frames in R for big data analytics. #rprogramming #bigdata #datascience

R Programming is like adding hot sauce to a bland dish 🌶️. Adding columns and combining data frames in R is as essential as salt in a recipe. Just like a DJ mixing beats, we gotta mix and match to create the perfect blend 💿. It’s all about spicing up the data and making it fire 🔥!

📝 Summarizing the Text

In this video, the R programming expert demonstrates how to add salaries to the existing employee data frame. The process involves appending a new column to the data frame and combining new employee data with the existing table. The presenter uses code examples to illustrate the steps involved in adding and combining data in R.

📊 Adding Salaries to Employee Data Frame

The first task involves entering the salaries of 10 employees in R. To do this, we need to know how to append new columns to an existing data frame. The initial data frame includes columns for serial numbers and employee names. It is necessary to add a new column for employee salaries. The presenter uses the data.frame function to create the initial data frame and then demonstrates how to append a salary column to the existing data frame using R code.

Key Takeaways: The process of adding new columns to an existing data frame in R involves creating a new variable for the column and using the $ operator to store values in the new column.

🧾 Combining Data Frames

In the next part of the video, the data analyst discusses combining the existing employee data with the salaries of five new employees. This process involves creating a new data frame for the new employee data and then using the rbind function to join the old and new data frames. The presenter provides a code example to demonstrate how to combine the two data frames, resulting in the final output with the salaries of the new employees included.

Key Takeaways: The rbind function is used to combine the existing employee data with the new employee data, resulting in a single, combined data frame.

Conclusion

In conclusion, this video provides a detailed demonstration of how to add salaries to an existing employee data frame in R. By following the examples and explanations provided, viewers can easily understand and implement the process of appending and combining data in R.

📌 Key Takeaways

• The process of adding new columns to an existing data frame in R involves creating a new variable for the column and using the $ operator to store values in the new column.
• The rbind function is used to combine the existing employee data with the new employee data, resulting in a single, combined data frame.
