Dear BioC Users,
When Affycomp gives a MA plot, there are both negative and positive infinities (in black ink) as plotting symbols on the plot. I noticed that they are also present on the example MA plots in the Cope, et.al (2005) paper. I have been unable to find an explanation of what these mean, and would appreciate it if someone could tell me what they represent. On a related note, is placement of these positive and negative infinities related to the performance of the method?
