I have been using beadarray to explore 5 Illumina mouse 6 bead chips (i.e. 30 arrays). I would now like to summarise the data using createBeadSummaryData. As the documentation says, this is memory intensive and I do not believe it will be possible to do with with a 32-bit version of R. I am looking into the possibility of being able to use a 64-bit compilation. However, this may take some time. So I was attracted by the help for this function which says: " Objects which are created separately by 'createBeadSummaryData' may be joined by using the cbind function. " I don't know what the trick is, but this doesn't work for me. I just wind up with a 1x2 matrix containing the names of the two bead summary objects I am trying to combine. Here is my code and session information. Thanks for any help.

Hi Krys, Sorry, it seems that the manual page for createBeadSummaryData is either out of date or contains a typo. The function we use to join summarised data is actually called combine so you would use BSData = combine(BSData39ABC, BSData39DEF) to get the required result. Hope this helps and thanks for bringing it to my attention Regards, Mark On 8 Aug 2007, at 17:07, Krys Kelly wrote: > I have been using beadarray to explore 5 Illumina mouse 6 bead > chips (i.e. > 30 arrays).
