In ggbio: Visualization tools for genomic data

Description

A set of simple navigation API apply to ggbio object, let you move along the genome and zoom in/out.

Usage

zoom(fac = 1/2)
zoom_in(fac = 1/2)
zoom_out(fac = 2)
nextView(unit = c("view", "gene", "exon", "utr"))
prevView(unit = c("view", "gene", "exon", "utr"))

Arguments

fac	numeric value to indicate zoom factor, multiple of current view width. If it's smaller than 1, then it's zoom-in operation; if it's bigger than 1, then it's zoom-out operation.
unit	only support 'view' unit now.

Details

zoom_in and zoom_out are just simple wrapper around zoom function.

For more convenient, gene features based jumpting we will support it in the future.
