### Программа дисциплины

#### Аннотация

In this media-oriented intermediate R course, you will learn how to apply graphs and network theory to social media, tokenize and quantitatively assess publications and expressions. and use mathematical methods to enhance your modeling skills. By the end of the course, you will be familiar with the basics of manipulating datasets to perform analytics in R.

#### Цель освоения дисциплины

• To provide an introduction to applications of R in journalism and political science and enable students to carry out research in a reproducible fashion.

#### Результаты освоения дисциплины

• Skill of using tidyverse, ggplot2
• Skill of interpreting text and media as big data.
• Skill of detecting the points of the most and the least optimistic SOTUs and to compare sentiment of speeches by political party.
• Skill of using the ‘rgraph’ library to manipulate a network structure.
• Skill of visualizing the network structure of VK friends.
• Skill of using logistic regression.
• Skill of evaluation of model predictive accuracy.
