An RGChannelSet, a MethylSet or a
matrix. We either use the getBeta function to get
Beta values (for the first two) or we assume the matrix contains
Beta values.
sampGroups
Optional sample group labels. See details.
main
Plot title.
xlab
x-axis label.
pal
Color palette.
xlim
x-axis limits.
ylim
y-axis limits.
add
Start a new plot?
legend
Plot legend.
...
Additional options to be passed to the plot command.
Details
This function produces the density plot component of the QC report. If sampGroups is specified, group-specific colors will be used.
Value
No return value. Plots are produced as a side-effect.
if (require(minfiData)) {
groups <- pData(RGsetEx)$Sample_Group
densityPlot(RGsetEx, sampGroups=groups)
}
