plotXY {beadarray} | R Documentation |
Function which produces an XY plot of the intensities from two specified arrays.
plotXY(exprs,array1=1, array2=2, genesToLabel=NULL, labelCol="red", log=TRUE,labelpch=16, foldLine=2,sampleSize=NULL,...)
exprs |
a matrix of expression values |
array1 |
integer specifying the first array to plot |
array2 |
integer specifying the second array to plot |
genesToLabel |
vector of genes to highlight on the plot.
These must match the rownames of exprs . |
labelCol |
plotting colours for highlighted genes |
log |
if TRUE the data will be log-transformed before plotting |
labelpch |
plotting characters for highlighted genes |
foldLine |
a numeric value defining where to fold change lines on the plot |
sampleSize |
The number of genes to plot. Default is NULL, which plots every gene. |
... |
other graphical parameters to plot that can be specified |
Plots the array1
intensities versus the array2
intensities for all probes.
A smoothed scatter plot is displayed on the current graphical device
