This function takes the result of a call to correctCopyNumber and
plots the results.
Usage
plotCorrectedCN(CN, chr=NULL)
Arguments
CN
object result of a call to correctCopyNumber.
chr
chromosome to plot.
Details
A panel with four plots is created. The top panel shows LRR (with
DNAcopy segmentation overlayed) and BAF before correction and the
bottom panel shows the plots after correction.
Value
No value is returned.
