In tengfei/ggbio: Visualization tools for genomic data

Tabulate a GRanges object

Description

Tabulate a GRanges object

Usage

## S4 method for signature 'GRanges'
stat_table(data, ..., xlab, ylab, main,
            geom = NULL,stat = NULL)
## S4 method for signature 'GRangesList'
stat_table(data, ..., xlab, ylab, main,
            facets = NULL, geom = NULL)

Arguments

data	A GRanges or data.frame object.
...	Extra parameters such as aes() passed to geom_rect, geom_alignment, or geom_segment.
xlab	Label for x
ylab	Label for y
main	Title for plot.
facets	Faceting formula to use.
geom	The geometric object to use display the data.
stat	The geometric object to use display the data.

Value

A 'Layer'.
