| glyphs {GGally} | R Documentation |
Create the data needed to generate a glyph plot.
glyphs(data, x_major, x_minor, y_major, y_minor, polar = FALSE, height = rel(0.95), width = rel(0.95), y_scale = identity, x_scale = identity)
data |
A data frame containing variables named in |
x_major,x_minor,y_major,y_minor |
The name of the variable (as a string) for the major and minor x and y axes. Together, each unique |
polar |
A logical of length 1, specifying whether the glyphs should
be drawn in polar coordinates. Defaults to |
height,width |
The height and width of each glyph. Defaults to 95% of
the |
y_scale,x_scale |
The scaling function to be applied to each set of
minor values within a grid cell. Defaults to |
