INTRODUCTION
3. WHY R?
R is a free, open-source programming language
widely used for data analysis and visualization. R
provides a wide range of statistical and graphical
techniques, making it a popular choice for data
scientists. Its vast community support and
availability of add-on packages make R a powerful
tool for data manipulation, analysis, and
visualization.
4. DATA TYPES IN R
R supports various data types, including
numeric, character, logical, and factor.
Understanding these data types is important for
data analysis. Numeric data types are used for
numerical calculations, character data types are
used for text, logical data types are used for
logical operations, and factor data types are
used for categorical data.
5. Data visualization is an important part of data
analysis. R provides a wide range of graphical
techniques that can be used to present data
effectively. These techniques include bar
graphs, line charts, scatterplots, and heat maps.
Data visualization helps in identifying patterns
and trends in data.

6. DATA ANALYSIS
R provides a wide range of statistical
techniques that can be used for data analysis.
These techniques include descriptive statistics,
hypothesis testing, regression analysis, and
machine learning. R also provides tools for data
cleaning and data manipulation, making it
easier to analyze data effectively.
7. CONCLUSION
In conclusion, mastering data analysis is essential for making informed
business decisions. R programming language provides a powerful tool for data
analysis and visualization. By understanding the basics of R and its wide
range of statistical and graphical techniques, you can analyze data effectively
and make informed decisions.
