Overview of this book

<p>Julia is an easy, fast, open source language that if written well performs nearly as well as low-level languages such as C and FORTRAN. Its design is a dance between specialization and abstraction, providing high machine performance without the sacrifice of human convenience. Julia is a fresh approach to technical computing, combining expertise from diverse fields of computational and computer science.</p> <p>This video course walks you through all the steps involved in applying the Julia ecosystem to your own data science projects. We start with the basics and show you how to design and implement some of the general purpose features of Julia. Is fast development and fast execution possible at the same time? Julia provides the best of both worlds with its wide range of types, and our course covers this in depth. You will have organized and readable code by the end of the course by learning how to write Lisp style macros and modules.</p> <p>The course demonstrates the power of the DataFrames package to manage, organize, and analyze data. It enables you to work with data from various sources, perform statistical calculations on them, and visualize their relationships in different kinds of plots through live demonstrations.</p> <p><em>Julia for Data Science</em> takes you from zero to hero, leaving you with the know-how required to apply</p> <h1>Style and approach</h1> <p>This course provides in-depth content balanced with functional tutorials that put theory into practice. The focus of this course is to give you both a technical understanding and the practical experience that will allow you to use Julia for data science projects.</p>

Section 2
Using DataArrays and DataFrames
Working with tabular data in matrices is possible, but not very convenient. The DataFrame offers us a more convenient data structure for data science purposes. - We need a way to deal with ‘Not Available’ values. This is dealt with in a DataArray - DataFrames are composed of DataArrays. We explore different ways to construct a DataFrame - We learn how to view parts of a DataFrame and how to get important info about its structure
