There are a number of text conventions used throughout this book.
CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "This script loads in RDatasets (this contains several standard datasets commonly used in data science)."
A block of code is set as follows:
Pkg.add("RDatasets")
using RDatasets
describe(dataset("datasets", "iris"))
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
var msg = "Hello, World"
console.log(msg)
Any command-line input or output is written as follows:
python2 -m pip install ipykernel
python2 -m ipykernel install --user
Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Once you select the Install button, Anaconda will automatically install R in your environment."
