Comment: C: Limma weights, non-specific interactions
... I agree, I would be making some very arbitrary choices here that could affect the analysis is unpredictable ways. I really like the idea of using a vector argument to lfc. I will play around with this. Removing the problematic interactors wouldn't work in our case since there may still be some biolo ...

Comment: C: Limma weights, non-specific interactions
... Sorry for my delay in responding. The array is a functional protein array and interactions with the "prey" (proteins printed on the array) are detected by an antibody to the "bait" (what was put on the array). A non-specific interaction would be caused by "stickiness" of the prey. In general, we wou ...

Limma weights, non-specific interactions
... Hi all, I am developing an analysis of protein microarray data and have found that limma performs very well in terms of identifying positive controls in the assay. Unfortunately, there are a large number of known, non-specific interactors that previous people have been identified in earlier experime ...

Comment: C: Difficulty extending ExpressionSet
... Thanks! I guess I had assumed that since no initialize method was defined for the subclass it would pass all its arguments unchanged to the parent class initialize method, like an implicit callNextMethod. I need to look more into SummarizedExperiment and how difficult it would be to interoperate wit ...

Comment: C: Difficulty extending ExpressionSet
... I see what you're saying. After looking over the code for the RccSet class definition a bit, it looks like they had to create a new assayData environment instance out of a matrix before calling the ExpressionSet constructor and made a bunch of methods to cover their bases depending on the input. How ...

Difficulty extending ExpressionSet
... Hello, This question was asked here previously around 7 years ago (https://support.bioconductor.org/p/36937/), however the answer seems to have either changed or the problem I'm facing is not the same. I am trying to write a class that extends ExpressionSet. I keep running into the following error: ...
