Conventions

Code, database table names, file and folder names, file extensions, pathnames, URLs, user input, and Twitter handles are shown as follows: "The pre-loaded datasets of R can be viewed using the data() command"

A block of code is set as follows:

# Installing necessary packages

install.packages("mlbench")

install.packages("caret")

# Loading the datasets

data(package = .packages(all.available = TRUE))

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: "The Help tab will display all the information about the dataset. "
