ggtext: Grob function: text

In hadley/ggplot1: Before there was ggplot2

Grob function: text

Description

Aesthetic mappings that this grob function understands:

• x:x position (required)

• y:y position (required)

• label:text label to display

• size:size of the text, as a multiple of the default size, (see scsize)

• rotation:angle, in degrees, of text label

• colour:text colour (see sccolour)

Usage

ggtext(plot, aesthetics = list(), ..., data = NULL)

Arguments

plot	the plot object to modify
aesthetics	named list of aesthetic mappings, see details for more information
...	other options, see details for more information
data	data source, if not specified the plot default will be used

Details

These can be specified in the plot defaults (see ggplot) or in the aesthetics argument. If you want to modify the position of the points or any axis options, you will need to add a position scale to the plot. These functions start with ps, eg. pscontinuous or pscategorical

Other options:

• justification:justification of the text relative to its (x, y) location, see textGrob for more details

Examples

p <- ggplot(mtcars, aesthetics=list(x=wt, y=mpg, labels = rownames(mtcars)))
ggtext(p)
ggtext(p, list(size=wt))
scsize(ggtext(p, list(size=wt)), c(0.5, 1.5))
ggtext(p, list(colour=cyl))
