Plots using bead level data to discover spatial effects and artifacts on arrays
SAMSummary(BLData, mode = "outliers", whatToPlot = "G", samID = NULL, log = TRUE, n = 3, colour = TRUE, scale = NULL, low = "yellow", high="red", ...) BeadChipSummary(BLData, mode = "outliers", whatToPlot = "G", chipID = NULL, stripsPerChip = 12, log = TRUE, n = 3, colour = TRUE, scale = NULL, low = "yellow", high = "red", ...)
BLData |
BeadLevelList object |
mode |
character string either "outliers" or "intensities" specifying what to display on the plots |
whatToPlot |
character string specifying which intensities to plot.
Possibilities are "G" , "Gb" for single channel data
and "G" , "Gb" , "R" and "Rb" for
two-colour data |
samID |
character string specifying which SAM to plot. If NULL , data from the first SAM is plotted. |
chipID |
character string specifying which BeadChip to plot. If NULL , data from the first BeadChip is plotted. |
stripsPerChip |
integer specifying number of strips on BeadChip (8 or 12) |
log |
if TRUE log2 intensities of each bead are used to find outliers |
n |
Specify a cut-off for outliers as n median absolute deviations from the median. The default value is 3 |
colour |
if TRUE the hexagons will be plotted in colour |
scale |
numeric value giving the amount by which to divide all numbers by (eg for log2 intensities this should be 16) to transform to range 0 - 1 |
low |
Color for area of lowest intensity |
high |
color for area of highest intensity |
... |
other parameters to imageplot that can be specified |
A plot will be displayed giving a summary of each array in the experiment on the left screen and initially a blank right hand side. The left hand side is coloured according to the number of outliers found on the array or the mean intensity of the array (depending on the mode parameter). Clicking on tha particular array on the left will display a location plot of the outliers or an image plot on the right See RNews article
Plot will be produced on the current graphical device
