Plot splitting the screen into two. The top windows displays the entire chromosome, whilst the bottom plots a selected region. The plot is interactive allowing the user to click twice on a chromosome in the upper plot and have it the region between the two clicks displayed below.

Usage

zoomChromosome(..., array = 1, chrom.to.plot, colors = NULL, chrominfo = chrominfo.Mb, ylim = c(-2, 2))

Arguments

...
Objects of type MAList or SegList
array
Specify which array should be plotted.
chrom.to.plot
Which chromosome should be plotted
colors
Vector specify the colors for each of the SegLists
chrominfo
chromosomal information associated with the mapping of the data.
ylim

Details

If colors is unspecified then all SegLists passed to this function will be plotted in blue. Since this makes it quite hard to tell which is which it is highly recommended to specify the colors vector if more than one object is being passe to this function.
