Bracket
Aesthetic mappings supported by geomBracket().
Parameters
Left end of the bracket for horizontal brackets.
Right end of the bracket for horizontal brackets.
Y-axis coordinate for horizontal brackets.
Lower end of the bracket for vertical brackets.
Upper end of the bracket for vertical brackets.
X-axis coordinate for vertical brackets.
Length of the tip at the bracket start (at xmin for horizontal brackets, or ymin for vertical brackets).
Length of the tip at the bracket end (at xmax for horizontal brackets, or ymax for vertical brackets).
Text to add.
Font size.
Type of the bracket line. Accept codes or names (0 = "blank", 1 = "solid", 2 = "dashed", 3 = "dotted", 4 = "dotdash", 5 = "longdash", 6 = "twodash"), a hex string (up to 8 digits for dash-gap lengths), or a pattern offset to listOf(dash, gap, ...) / listOf(dash, gap, ...). For more info see: aesthetics.html#line-types.
Color of the geometry. For more info see: aesthetics.html#color-and-fill.
Transparency level of a layer. Accept values between 0 and 1.
Font family. For more info see: aesthetics.html#text.
Font style and weight. For more info see: aesthetics.html#text.
Horizontal text alignment relative to the x-coordinate. Possible values: 0 or "left" - left-aligned (text starts at x), 0.5 or "middle" (default) - text is centered on x, 1 or "right" - right-aligned (text ends at x). There are two special alignments: "inward" (aligns text towards the plot center) and "outward" (away from the plot center).
Vertical text alignment relative to the y-coordinate. Accept either a numeric value or one of: "bottom", "center", or "top". The numeric values 0, 0.5 (default), and 1 correspond to "bottom", "center", and "top", respectively. There are two special alignments: "inward" (aligns text towards the plot center) and "outward" (away from the plot center).
Text rotation angle in degrees.
Line height multiplier applied to the font size in the case of multi-line text.
Color of the bracket line (the segments forming the bracket). For more info see: aesthetics.html#color-and-fill.
Width of the bracket line (the segments forming the bracket).
Transparency level of the bracket line. Accept values between 0 and 1.
Grouping key. If not set, grouping may be inferred from other aesthetics (e.g., color, size).
Auxiliary paint channel A that can be used as either color or fill as needed. Map a variable here for composite/multi-channel color with a matching scale.
Auxiliary paint channel B. See paint_a.
Auxiliary paint channel C. See paint_a.
