# Chapter 7 Titles

## 7.1 Plot title

Plot titles are very important for presenting your visualizations. You can set the plot title by title.

superheat(mtcars,
# scale the matrix columns
scale = TRUE,
# plot title
title = "Superheat for mtcars",
title.size = 8)

Note that the default plot title is left-aligned. This can be changed using the title.alignment argument whose options are left, center, and right.

superheat(mtcars,
# scale the matrix columns
scale = TRUE,
# plot title
title = "Superheat for mtcars",
title.alignment = "center")

## 7.2 Row and column titles

Adding titles to the columns and rows is easy too. Simply supply the desired row and column titles for the row.title and column.title arguments

superheat(mtcars,
# scale the matrix columns
scale = TRUE,
# row title
row.title = "Cars",
row.title.size = 6,
# col title
column.title = "Variables",
column.title.size = 6)
