Loon's displays that are based on Cartesian coordinates (i.e. scatterplot, histogram and graph display) allow for layering visual information including polygons, text and rectangles.

l_layer_texts(widget, x, y, text, color = "gray60", size = 6,
  angle = 0, label = "texts", parent = "root", index = 0, ...)

Arguments

x

the coordinates of line. Alternatively, a single plotting structure, function or any R object with a plot method can be provided as x and y are passed on to xy.coords
