Filled trapezoid connecting two tracks

Source: R/seq_synteny.R
seq_synteny.Rd

Draws a filled quadrilateral whose bottom edge spans a region in track t0 and whose top edge spans a homologous region in track t1. Use to highlight syntenic blocks, orthologous segments, or otherwise paired intervals across two stacked tracks.

Usage

seq_synteny(
  data = NULL,
  mapping = NULL,
  t0 = NULL,
  t1 = NULL,
  aesthetics = aes(),
  ...
)

Arguments

data

Optional GRanges or data.frame.

mapping

Optional map().

t0, t1

Track identifiers. Locked to the parent track when added inside a seq_track().

aesthetics

Optional aes(): fill / color (fill color), alpha (default 0.4), linewidth (border width).

...

Reserved.

Value

A SeqSyntenyR6 instance.

Details

data may be a GRanges or a data.frame. Required map() fields are x0 and x1; x0_end and x1_end default to one base past x0/x1 when absent. y0 and y1 default to the bottom edge of t0's inner panel and the top edge of t1's inner panel respectively — no scale conversion is applied in that case.
