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.
patternPattern name string e.g. 'stripe' (default), 'crosshatch', 'point', 'circle', 'none'
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_yoffsetOffset 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 Alpha transparency for pattern. default: 1
pattern_linetype Stroke linetype. default: 1
pattern_size Stroke line width. default: 1
pattern_option_1 Generic User value
