geom
Plots the sum of the y and height aesthetics versus x. Heights of the ridges are relatively scaled.
Notes
Computed variables:
..height.. : density scaled for the ridges, according to area, counts or to a constant maximum height.
..density.. : density estimate.
..count.. : density * number of points.
..scaled.. : density estimate, scaled to maximum of 1.
..quantile.. : quantile estimate.
To hide axis tooltips, set "blank" or the result of elementBlank() to the axisTooltip or axisTooltipX parameter of the theme().
Examples
Parameters
The data to be displayed in this layer. If null, the default, the data is inherited from the plot data as specified in the call to letsPlot.
default = Stat.densityRidges(). The statistical transformation to use on the data for this layer. Supported transformations: Stat.identity, Stat.bin(), Stat.count(), etc. see Stat.
Position adjustment: positionIdentity, positionStack(), positionDodge(), etc. see Position.
default = true. false - do not show legend for this layer.
default = true. false - do not combine the layer aesthetic mappings with the plot shared mappings.
String or result of the call to the layerKey() function. The key to show in the manual legend. Specifies the text for the legend label or advanced settings using the layerKey() function.
Result of the call to the samplingXxx() function. To prevent any sampling for this layer pass value samplingNone. For more info see sampling.html.
Result of the call to the layerTooltips() function. Specifies appearance, style and content. Set tooltips = tooltipsNone to hide tooltips from the layer.
X-axis coordinates.
Y-axis coordinates.
Height of the ridge. Assumed to be between 0 and 1, though this is not required.
Quantile values to draw quantile lines and fill quantiles of the geometry by color.
Transparency level of a layer. Understands numbers between 0 and 1.
Color of the geometry. For more info see: aesthetics.html#color-and-fill.
Fill color. For more info see: aesthetics.html#color-and-fill.
Type of the line of border. 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.
Defines line width.
Used by Stat.densityRidges() stat to compute weighted density.
default = 1.0 A multiplicative factor applied to height aesthetic. If scale = 1.0, the heights of a ridges are automatically scaled such that the ridge with height = 1.0 just touches the one above.
default = 0.0. A height cutoff on the drawn ridges. All values that fall below this cutoff will be removed.
default = false. Shows the quantile lines.
Extends domain of each ridge on tailsCutoff * bw if trim = false. tailsCutoff = null (default) extends domain to maximum (domain overall ridges).
default = listOf(0.25, 0.5, 0.75). Draws horizontal lines at the given quantiles of the density estimate.
String or Double. The method (or exact value) of bandwidth. Either a string (choose among "nrd0" and "nrd") or a double.
The kernel we use to calculate the density function. Choose among "gaussian", "cosine", "optcosine", "rectangular" (or "uniform"), "triangular", "biweight" (or "quartic"), "epanechikov" (or "parabolic").
The number of sampled points for plotting the function.
default = false. Trims the tails of the ridges to the range of the data.
Adjusts the value of bandwidth by multiplying it. Changes how smooth the frequency curve is.
Maximum size of data to use density computation with "full scan". For bigger data, less accurate but more efficient density computation is applied.
default = "color" ("fill", "color", "paint_a", "paint_b", "paint_c"). Defines the color aesthetic for the geometry.
default = "fill" ("fill", "color", "paint_a", "paint_b", "paint_c"). Defines the fill aesthetic for the geometry.
Set of aesthetic mappings. Aesthetic mappings describe the way that variables in the data are mapped to plot "aesthetics".
