The simplex key is equivalent to the polygon key except that
it renders triangles rather than squares. This evokes the triangularity
of simplices and distinguishes plots from plots of arbitrary polygons.
draw_key_simplex(data, params, size)Arguments
- data
A single row data frame containing the scaled aesthetics to display in this key
- params
A list of additional parameters supplied to the geom.
- size
Width and height of key in mm.
Examples
# regular septagon
sevenths <- (seq_len(7) - 1) * 2 * pi / 7
septagon <- data.frame(x = cos(sevenths), y = sin(sevenths))
ggplot(septagon, aes(x, y)) +
geom_simplicial_complex(
diameter = 1.6, dimension_max = 5L, one_simplices = "all",
engine = "simplextree",
aes(color = after_stat(factor(dimension)),
fill = after_stat(factor(dimension))),
alpha = .5
)
# regular pentagon
fifths <- (seq_len(5) - 1) * 2 * pi / 5
pentagon <- data.frame(x = cos(fifths), y = sin(fifths))
ggplot(pentagon, aes(x, y)) +
