Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "As an example, we use the data-file winequality.csv that contains 1599 sample measurements, 12 data columns."

A block of code is set as follows:

using DataFrames
fname = "winequality.csv"
data = readtable(fname, separator = ';')

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

using DataFrames
fname = "winequality.csv"
data = readtable(fname, separator = ';')

Any command-line input or output is written as follows:

julia main.jl

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Navigate to Configuration | System Administration | ODBC Data Sources."
