Bracket Dodge Parameters
Properties for parameters of geomBracketDodge().
Parameters
default = 0. Symmetrically shorten the bracket by shifting both ends toward the center. Expects values between 0 and 1, where 0 corresponds to no shortening and 1 to a fully collapsed bracket.
default = "size" ("res", "identity", "size", "px"). Unit for the lenstart and lenend aesthetics. Possible values:
"res": the unit equals the smallest distance between data points along the corresponding axis;
"identity": a unit of 1 corresponds to a difference of 1 in data space;
"size": a unit of 1 corresponds to the diameter of a point with
size = 1;"px": the unit is measured in screen pixels.
default = 0.95. Width used to compute bracket positions. Expected to match the dodge width used by other layers for proper alignment.
Total number of dodged groups per category; used to interpret istart/iend indices. By default, this value is inferred from the data when possible, but can be set explicitly if needed.
