Description Usage Arguments Details See Also
ref_box creates a layer of reference boxes to be plotted behind a layer of
glyphs. Each box spans the full width and height of the glyph. Reference
boxes make it easier to determine the location of an object within a glyph
and to compare objects across glyphs. Reference boxes can also convey
information on their own through fill, colour, alpha, linetype, and (line)
size mappings. By default the fill and colour parameters of a reference box
match the grey and white color scheme of ggplot2 panels in
theme_grey
.
