and qplot
for how to create a complete plot from individual components.
A layer
The following aesthetics can be used with geom_text. Aesthetics are mapped to variables in the data with the aes
function: geom\_text(\code{aes}(x = var))
x
: x position (required)
y
: y position (required)
label
: text label (required)
colour
: border colour
size
: size
angle
: angle
hjust
: horizontal justification, between 0 and 1
vjust
: vertical justification, between 0 and 1
