spkDensity {spkTools} | R Documentation |
A density plot of the non-spike-in expression with a rug of the average expression at each spike-in level.
spkDensity(object, spkSlopeOut, cuts=TRUE, label = NULL, ...)
object |
a SpikeInExpressionSet object |
spkSlopeOut |
the output from the spkSlope function |
cuts |
if TRUE vertical lines are drawn at the expression values separating low vs medium and medium vs high ALE strata |
label |
a character string to insert into the plot title |
... |
arguments passed to the plot function |
This function requires the output of spkSlope.
Density plot is produced.
