[BioC] PlotMA

[James MacDonald]

The help for plotMA (found by typing ?plotMA at an R prompt with the
limma package loaded) says the following:

Arguments:

      MA: an 'RGList', 'MAList' or 'MArrayLM' object, or any list with
          components 'M' containing log-ratios and 'A' containing
          average intensities

   array: integer giving the array to be plotted. Corresponds to
          columns of 'M' and 'A'.

So it looks like you need to set array = 2, etc to do the other MA
plots.

HTH,

Jim

Dear all:

I read 12 cDNA experimental data into RGwt, when I use plotMA, only 1
shows up, how do I show others? I can't find documentation for it
anywhere.

Thanks

Hao Liu, Ph. D
