Conventions

In this book, you will find a number of styles of text 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: "The legend() command is very powerful and provides many options to create and place legends."

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

qplot(HEIGHT, WEIGHT_1, data = T, main = "HEIGHT vs. WEIGHT", xlab = "HEIGHT (cm)", ylab = "WEIGHT BEFORE TREATMENT (kg)" , geom = "point" , colour = factor(ETH), size = 2, alpha = I(0.7))

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Note the use of the assigns operator, which consists of the less than sign followed by a minus sign."
