stat
Displays a smoothed conditional mean.
Notes
statSmooth() aids the eye in seeing patterns in the presence of overplotting.
Computed variables:
..y.. : predicted (smoothed) value.
..ymin.. : lower pointwise confidence interval around the mean.
..ymax.. : upper pointwise confidence interval around the mean.
..se.. : standard error.
To hide axis tooltips, set "blank" or the result of elementBlank() to the axisTooltip or axisTooltipX parameter of the theme().
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.
The geometry to display the smooth stat for this layer, default is smoothed line, see Geom.
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.
Result of the call to the samplingXxx() function. To prevent any sampling for this layer pass value samplingNone. For more info see sampling.html.
X-axis value.
Predicted (smoothed) value.
Lower pointwise confidence interval around the mean.
Upper pointwise confidence interval around the mean.
Lines width.
Type of the 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.
Fill color. For more info see: aesthetics.html#color-and-fill.
Transparency level of a layer. Understands numbers between 0 and 1.
default = "lm". Smoothing method: lm (Linear Model) or loess (Locally Estimated Scatterplot Smoothing).
default = 80. Number of points to evaluate smoother at.
default = 0.95. Level of confidence interval to use.
default = true. To display confidence interval around smooth.
default = 0.5. Only for LOESS method. The fraction of source points closest to the current point is taken into account for computing a least-squares regression. A sensible value is usually 0.25 to 0.5.
default = 1. Degree of polynomial for linear regression model.
Random seed for LOESS sampling.
default = 1000. Maximum number of data-points for LOESS method. If this quantity exceeded random sampling is applied to data.
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".
