[BioC] beadarray: how to apply imageplot() on BLData-outliers ?

[Christian Kohler]

Dear all,

after unsuccessfully spending some hours on the following problem, I
would like to ask for your help.

My current situation:
I have read in several illumina tif-files into one BLData object; then I
applied findAllOutliers() to every array within this object.
The result looks like this:

>List of 21
 $ : int [1:45382] 34 47 52 55 123 125 131 141 153 159 ...
 $ : int [1:50858] 4 10 28 32 34 43 61 79 114 115 ...
 $ : int [1:49176] 1 7 19 32 46 49 55 68 69 75 ...
.
.
.
.
The above list contains the index of each outlier of each array.

My problem:
Is it possible to apply the imageplot()-function to a subset of the
BLData object above?
I mean, imageplot() takes a whole BLData object (including outliers) but
I would like to only draw the intensity (and therefore the location) of
the outliers. (question to experts: does a plot like this make sense
anyway?)
How can I extract the outlier-information from BLData and store the
'modified' information in another BLData object?


I am very happy for any suggestion.

Best,
Christian
