All geoms in this package are identical to their counterparts in ggplot2 except that they can be filled with patterns.
Not all arguments apply to all patterns.

pattern_colour
Colour used for strokes and points. default: 'black'
pattern_fill
Fill colour. default: 'black'
pattern_angle
Orientation of the pattern in degrees. default: 45
pattern_density
Approximate fill fraction of the pattern. Usually in range [0, 1], but can be higher. default: 0.2
pattern_spacing
Spacing of the pattern as a fraction of the plot size. default: 0.05
pattern_xoffset,pattern_yoffset
Offset the origin of the pattern. Range [0, 1]. default: 0. Use this to slightly shift the origin of the pattern. For most patterns, the user should limit the offset value to be less than the pattern spacing.
pattern_alpha

pattern_linetype
Stroke linetype. default: 1
pattern_size
Stroke line width. default: 1
