Select single probe-set with median expression from multiple probe-sets corresponding to same gene -AFFY
...level. I am fully aware that it is not a nice thing
to do but I just have to do it.
To do so, I came across 'findLargest' function of 'genefilter' package
but it's not well documented; and I do not know how to implement the
'findLargest' function. At this point I have:
esetRMA <- rma(mydata)
Could anybody guide me on how can I select single probeset with median
expression from multiple probe-sets corresponding to single gene and
discard others? Is there any other way to achieve so i.e. other than
using 'genefilter'?
