Draw a kernel density estimate as a filled area

Source: R/seq_density.R
seq_density.Rd

Composite element that computes stats::density() of the resolved y values and renders the distribution as a filled area. The density evaluation axis (the distribution of y values) is drawn horizontally across the panel using the track's yscale; densities are normalised to the panel height.

Usage

seq_density(data = NULL, mapping = NULL, aesthetics = aes(), ...)

Arguments

data

Optional GRanges.

mapping

Optional SeqMap. Required field: y.

aesthetics

Optional SeqAes. Supports fill, color, alpha, linewidth, and bw (kernel bandwidth, default "nrd0").

...

Additional arguments reserved for future use.

Value

A SeqDensityR6 instance.
