[Bioc-devel] limma and NChannelSet
Audrey Kauffmann wrote:
Dear all,
As far as I know, RGList is the format expected from most limma
functions to handle two colour arrays. I was wondering if there is a
plan to make it possible to use limma functions on NChannelSet objects?
Also, is the following the best way to convert a NChannelSet (NCS) into
a RGList?
RG <- new("RGList", list(R = assayData(NCS)$R, G = assayData(NCS)$G))
Hi Audrey --
Unfortunately, NChannelSet doesn't specify the names of the channels, so
there is no certainty that it contains R and G.
The 'convert' library defines a method as(rglist, "NChannelSet") which
might provide additional data to be moved between classes, e.g.,
library(convert)
selectMethod(coerce, c("RGList", "NChannelSet"))

Thank you, Audrey
