StatDensityWatercolor.RdThis function creates a confidence envelope for the empirical density by bootstrapping from the data. Transparency is used to indicate the level of uncertainty.
An object of class StatDensityWatercolor (inherits from Stat, ggproto, gg) of length 4.
Number of bootstrapped smoothers. The default is 1000.
Color for the bootstrapped densities that make up the confidence envelope. The
default is color="#1D91C0"
Transparency level for the paths that make up the bootstrapped fitted lines. This may
need to be adjusted if the argument k= is changed. The default value is alpha=0.03.
The model to bootstrap from. The default is model="none" which bootstraps from the data.
