Summary

Markdown supported

In this presentation, Barbara Fusińska discusses the R language and its application in analyzing GitHub comments. She highlights her personal journey with R, emphasizing the importance of choosing interesting domains for analysis rather than typical introductory examples.

Key Points Discussed:
- **Introduction to R**: R was created by Ross Ihaka and Robert Gentleman at Bell Labs and is popular in the data science field alongside Python. 
- **Why Use R**: R is a great choice for programmers interested in data transformation, exploration, and machine learning. Its robustness in statistical analysis is one of its key features.
- **Getting Started**: Users need to download R and can use various editors. RStudio is recommended for its user-friendly interface.
- **Basics of R**: R is unique as it handles everything as vectors. The language's syntax may initially confuse users with its use of arrows for assignments and indexing practices. 
- **Data Structures**: R utilizes various data structures like vectors, lists, and data frames, each serving specific functions. Data frames are especially important for analysis as they resemble tables in databases and allow mixed data types.
- **GitHub Comments Analysis**: Fusińska explores language distributions using GitHub's API. She discusses challenges like missing language data and how it can affect analyses.
- **Data Manipulation in R**: She illustrates functions for reading JSON data, filtering, and plotting the results to visualize language distribution effectively.
- **Community Support**: The commitment and contributions of the R community enhance its capabilities, making it beneficial for data scientists.

Fusińska encourages practice and exploration of R, noting its strengths in statistical analysis and data visualization. She concludes by reflecting on the gradual learning process associated with R and invites the audience to consider its use in future projects. 
Overall, the presentation aims to inspire interest in R and highlight its potential in data science.
