geom
Displays quantile-quantile plot.
Notes
The Q-Q plot is used for comparing two probability distributions (sample and theoretical) by plotting their quantiles against each other.
If the two distributions being compared are similar, the points in the Q-Q plot will approximately lie on the straight line.
Computed variables:
..theoretical.. : theoretical quantiles.
..sample.. : sample quantiles.
To hide axis tooltips, set "blank" or the result of elementBlank() to the axisTooltip, axisTooltipX or axisTooltipY 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.qq(). 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.
default = "norm". Distribution function to use: "norm", "uniform", "t", "gamma", "exp", "chi2".
Additional parameters passed on to distribution function.
If
distributionis "norm" thendParamsis a pair (mean, std) (default = listOf(0.0, 1.0)).If
distributionis "uniform" thendParamsis a pair (a, b) (default = listOf(0.0, 1.0)).If
distributionis "t" thendParamsis an integer number (d) (default = listOf(1)).If
distributionis "gamma" thendParamsis a pair (alpha, beta) (default = listOf(1.0, 1.0)).If
distributionis "exp" thendParamsis a float number (lambda) (default = listOf(1.0)).If
distributionis "chi2" thendParamsis an integer number (k) (default = listOf(1)).
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.
Y-axis value.
Transparency level of a layer. Understands numbers between 0 and 1.
Color of the geometry. For more info see: aesthetics.html#color-and-fill.
Color to paint shape's inner points. Is applied only to the points of shapes having inner points. For more info see: aesthetics.html#color-and-fill.
Shape of the point. For more info see: aesthetics.html#point-shapes.
Size of the point.
Width of the shape border. Applied only to the shapes having border.
Set of aesthetic mappings. Aesthetic mappings describe the way that variables in the data are mapped to plot "aesthetics".
