Textual annotations.

Textual annotations.

Usage
geom_text(mapping = NULL, data = NULL, stat = "identity",
  position = "identity", parse = FALSE, ...)
Arguments
mapping
The aesthetic mapping, usually constructed with aes or aes_string. Only needs to be set at the layer level if you are overriding the plot defaults.
data
A layer specific dataset - only needed if you want to override the plot defaults.
stat
The statistical transformation to use on the data for this layer.
position
The position adjustment to use for overlapping points on this layer
parse
If TRUE, the labels will be parsed into expressions and displayed as described in ?plotmath
...
other arguments passed on to layer. This can include aesthetics whose values you want to set, not map. See layer for more details.
Aesthetics

[results=rd,stage=build]{ggplot2:::rd_aesthetics("geom", "text")} p <- ggplot(mtcars, aes(x=wt, y=mpg, label=rownames(mtcars)))

p + geom_text() # Change size of the label p + geom_text(size=10) p <- p + geom_point()

# Set aesthetics to fixed value p + geom_text() p + geom_point() + geom_text(hjust=0, vjust=0) p + geom_point() + geom_text(angle = 45)

# Add aesthetic mappings p + geom_text(aes(colour=factor(cyl))) p + geom_text(aes(colour=factor(cyl))) + scale_colour_discrete(l=40)

p + geom_text(aes(size=wt)) p + geom_text(aes(size=wt)) + scale_size(range=c(3,6))

# You can display expressions by setting parse = TRUE. The # details of the display are described in ?plotmath, but note that # geom_text uses strings, not expressions. p + geom_text(aes(label = paste(wt, "^(", cyl, ")", sep = "")), parse = TRUE)

# Add an annotation not from a variable source c <- ggplot(mtcars, aes(wt, mpg)) + geom_point() c + geom_text(data = NULL, x = 5, y = 30, label = "plot mpg vs. wt") # Or, you can use annotate c + annotate("text", label = "plot mpg vs. wt", x = 2, y = 15, size = 8, colour = "red")

# Use qplot instead qplot(wt, mpg, data = mtcars, label = rownames(mtcars), geom=c("point", "text")) qplot(wt, mpg, data = mtcars, label = rownames(mtcars), size = wt) + geom_text(colour = "red")

# You can specify family, fontface and lineheight p <- ggplot(mtcars, aes(x=wt, y=mpg, label=rownames(mtcars))) p + geom_text(fontface=3) p + geom_text(aes(fontface=am+1)) p + geom_text(aes(family=c("serif", "mono")[am+1]))
