Reusable blocks of code that perform specific tasks and can be called from other parts of a program.
Operations performed on data to transform, filter, or summarize it, such as sorting, merging, and aggregating.
The graphical representation of data to help understand patterns, trends, and relationships.
Operations performed on files, such as reading from or writing to them, in order to store or retrieve data.
The process of identifying and fixing errors or bugs in a program.
Techniques used to handle and recover from errors or exceptions that occur during program execution.
Advanced concepts and techniques in R programming, such as object-oriented programming and parallel computing.
One-dimensional arrays that can hold elements of the same or different data types.
Two-dimensional arrays with rows and columns that can hold elements of the same or different data types.
Tabular data structures with rows and columns, similar to a spreadsheet or database table.
Data structures that can hold elements of different data types and can be nested within each other.
Statements that control the flow of execution in a program, such as if-else statements and switch statements.
Statements that repeatedly execute a block of code until a certain condition is met.
Collections of R functions, data, and documentation that extend the capabilities of the base R system.
The process of reading data from external sources, such as files or databases, into R.
The process of writing data from R to external sources, such as files or databases.
The process of identifying and correcting or removing errors, inconsistencies, or inaccuracies in data.
The process of converting data from one format or structure to another, such as reshaping or aggregating data.
Creating simple plots, such as scatter plots, line plots, and bar plots, to visualize data.
Creating complex plots, such as histograms, box plots, and heatmaps, with customized settings and annotations.
Reading data from files, such as CSV or Excel files, into R for further analysis or manipulation.
Writing data from R to files, such as CSV or Excel files, for storage or sharing with others.
Methods and tools used to identify and fix errors or bugs in R programs, such as using breakpoints and debugging functions.
A programming paradigm that organizes data and behavior into objects, which interact with each other through methods and properties.
The use of multiple processors or cores to perform computations simultaneously, improving performance and efficiency.
Organized and structured formats for storing and manipulating data, such as vectors, matrices, lists, and data frames.
The process of inspecting, cleaning, transforming, and modeling data to discover useful information and make informed decisions.
The application of statistical methods and techniques to analyze and interpret data, uncover patterns, and make predictions or inferences.
A branch of artificial intelligence that uses statistical techniques to enable computer systems to learn from data and make predictions or decisions without being explicitly programmed.
The process of discovering patterns, relationships, or insights from large amounts of data using techniques from statistics, machine learning, and database systems.
The creation and presentation of reports or summaries of data analysis results, often using visualizations or tables.
The communication of data analysis results to stakeholders or audiences, often using visualizations or interactive dashboards.
The process of making sense of data analysis results, drawing conclusions, and deriving insights or recommendations.
The organization and management of data for efficient storage, retrieval, and access, often using databases or data warehouses.
The protection of data from unauthorized access, use, disclosure, disruption, modification, or destruction, often through encryption or access controls.
The protection of personal or sensitive data from unauthorized collection, use, or disclosure, often through privacy policies or regulations.
The moral principles and guidelines for the responsible and ethical use of data, considering issues such as privacy, fairness, transparency, and accountability.
The overall management and control of data assets, including policies, processes, and standards for data quality, integrity, and security.
The process of combining data from different sources or systems into a unified view, often using ETL (Extract, Transform, Load) processes or tools.
The degree to which data meets the requirements or expectations for its intended use, including accuracy, completeness, consistency, and timeliness.
The process of collecting, organizing, and storing large amounts of data from different sources for analysis and reporting purposes.
