Dear Kirill,

Regarding the error I have already sent a mail to R-devel and am waiting 
for an answer. I will update xps as soon as I know the reason for this 

Regarding Windows 7 you need a ROOT version compiled with MinGW, as the 
README file mentions. Currently, you should be able to download this 
file from:

In case the download link does not work, I could send you the ROOT 
binary compiled with MinGW, i.e. root-mingw-O2.7z, however the size is 
35 MB.

Please uninstall the current version of ROOT before installing the 
correct one otherwise there may be problems. Please let me know if you 
can run xps on your Windows machine.

Best regards,

In arrayQualityMetrics report I can see table with detected outliers (such as here: http://www-huber.embl.de/arrayQualityMetrics/Report_for_nMLL_with_factors/). In the xps package I cannot make my report in pdf because I have some errors, only Rwd file and all images. Does pdf file contain more information than I see into the QC stats folder?

I used arrayQualityMetrics package before new version of R was avaliable which doesn't maintain affy package for ST arrays. ArrayQualityMetrics creates good report with "outliers" assays, which are out of borders (for example, cut-offs for NUSE is 1.1), but I've not seen this in xps.
