Description Usage Arguments Value Author(s) See Also Examples
Function to visualize spatial distribution of raw intensities on
NimbleGen Oligoarrays. Requires RGList
with component
genes
complete with genes$X
and genes$X
coordinates of probes on array.
arrayImage
is a synonym of image.RGList

## this example looks strange because the example data files only
## includes the probe intensities of probes mapped to the forward
## strand of chromosome 9.
## you can see these probes are distributed all over the array
