plotting: Lattice-style plots for granges and SnpArrayExperiment...
In rscharpf/VanillaICE: A Hidden Markov Model for high throughput genotyping arrays

Description Usage Arguments See Also Examples

Data for the graphic is generated by a call to grangesData.

xyplotList(granges, se, param = HmmTrellisParam())

## S4 method for signature 'HmmGRanges,SnpArrayExperiment'
xyplotList(granges, se,
  param = HmmTrellisParam())

## S4 method for signature 'GRangesList,SnpArrayExperiment'
xyplotList(granges, se,
  param = HmmTrellisParam())

xygrid(trellis_plot, viewports, granges)

`granges`	a `HmmGRanges` object
`se`	a `SnpArrayExperiment`
`param`	trellis parameters for plotting HMM
`trellis_plot`	an object of class `trellis`
`viewports`	a list of viewports as provided by the `viewports` function
