wimage.cpd {compdiagTools} | R Documentation |
Residuals are shown color coded according to their location on the chip in a two dimensional layout.
wimage.cpd(plmset, which, filename = NULL, ...) wimage.resids(sampleName, residuals, abo, pm.index, filename = NULLm, ...)
plmset |
affyPLM-object from which residuals are extracted. |
which |
which sample to choose, an integer number. |
sampleName |
the name of the samle to be shown. |
residuals |
residuals as from median polish as a vector of entries, one per probe. |
abo |
affyBatch object used to deduce chip properties. |
pm.index |
indeces for perfect match probes. |
filename |
writes a png-bitmap if this parameter is specified. |
... |
further arguments passed to 'bitmap. |
In this plot, you can see local artefacts which affected neighboring probes. A chip of good quality has no striking marks or taints.
