Draw tiles (rectangles or rotated diamonds)

Source: R/seq_tile.R
seq_tile.Rd

Composite element drawing one filled shape per genomic range. In the default unrotated mode, each tile is a rectangle spanning start..end on the x-axis at the row indicated by y (default 1). With aes(rotate = TRUE) and a data2 GRanges giving per-tile y-axis coordinates, tiles are rendered as diamonds via a linear coordinate transform in genomic space.

Usage

seq_tile(data = NULL, mapping = NULL, aesthetics = aes(), data2 = NULL, ...)

Arguments

data

Optional GRanges.

mapping

Optional SeqMap. Recognised fields: x, y, fill.

aesthetics

Optional SeqAes. rotate toggles diamond mode; fill sets a constant fill color.

data2

Optional GRanges providing y-axis genomic ranges for rotated mode. Must match data in length.

...

Additional arguments reserved for future use.

Value

A SeqTileR6 instance.
