This document contains examples of plots, FlexTables, and text generated with the ReporteRs package in R to create a PowerPoint presentation. A line plot is generated showing ozone levels over time. A FlexTable is created from the iris dataset with styled cells and borders. Sections of formatted text are added describing topics in data science, analytics, and machine learning.

• Data science is an interdisciplinary field about processes and
systems to extract knowledge or insights from data in various
forms, either structured or unstructured, which is a
continuation of some of the data analysis fields such as
statistics, machine learning, data mining, and predictive
analytics.
• Analytics is the discovery, interpretation, and communication
of meaningful patterns in data. Especially valuable in areas
rich with recorded information, analytics relies on the
simultaneous application of statistics, computer
programming and operations research to quantify
performance. Analytics often favors data visualization to
communicate insight.
• Machine learning is a type of artificial intelligence (AI) that
provides computers with the ability to learn without being
explicitly programmed. Machine learning focuses on the
development of computer programs that can teach
themselves to grow and change when exposed to new data.
