This program computes the frequency of gains and losses for each probe as a function of level of mad.

x |
an object of class DNAcopy. |
chrom |
the chromosome in which the region lies. |
sampleid |
the sample of interest. |
maploc.start |
genomic start position of the region of interest. Default is the beginning of the chromosome. |
maploc.end |
genomic end position of the region of interest. Default is the end of the chromosome. |
pt.pch |
the plotting character used for plotting the log-ratio values (default is "."). |
pt.cex |
the size of plotting character used for the log-ratio values (default is 3 if "." and 1 otherwise). |
pt.col |
the color used for the points. Default is green3. |
segcol |
the color of the lines indicating the segment means. If missing the line color is set to be red. |
seglwd |
line weight of lines for segment mean and zeroline. If missing it is set to 3. |
main |
figure title. If missing will be generated by pasting the chromosome, range and sample name together. |
xlab |
x-axis label. If missing "Genomic position" will be used |
ylab |
y-axis label. If missing "log-ratio" will be used |
... |
additional plotting options. |
This command plots the region of interest with the log-ratio and segments. It works for a region from a single chromosome in a single sample. So if more than one chromosome and/or one sample are given only the first chromosome from the first sample will be used.
