draw_text: Draw multiple text-strings in one go.

In cowplot: Streamlined Plot Theme and Plot Annotations for 'ggplot2'

Draw multiple text-strings in one go.

Description

This is a convenience function to plot multiple pieces of text at the same time. It cannot handle mathematical expressions, though. For those, use draw_label.

Usage

draw_text(text, x = 0.5, y = 0.5, size = 14, hjust = 0.5, vjust = 0.5, ...)

Arguments

text	A vector of Character (not expressions) specifying the string(s) to be written.
x	Vector of x coordinates.
y	Vector of y coordinates.
size	Font size of the text to be drawn.
hjust	(default = 0.5)
vjust	(default = 0.5)
...	Style parameters, such as colour, alpha, angle, size, etc.

Details

Note that font sizes are scaled by a factor of 2.85, so sizes agree with those of the theme. This is different from geom_text in ggplot2.

By default, the x and y coordinates specify the center of the text box. Set hjust = 0, vjust = 0 to specify the lower left corner, and other values of hjust and vjust for any other relative location you want to specify.

For a full list of ... options, see geom_label.

Examples

# Draw onto a 1*1 drawing surface
ggdraw() + draw_text("Hello World!", x = 0.5, y = 0.5)
#
# Adorn a plot from the Anscombe data set of "identical" data.
library(ggplot2)

p <- ggplot(anscombe, aes(x1, y1)) + geom_point() + geom_smooth()
three_strings <- c("Hello World!", "to be or not to be", "over and out")
p + draw_text(three_strings, x = 8:10, y = 5:7, hjust = 0)
