[Bioc-devel] Moving minfi classes definition to a lighter package

Dear Bioc developers,

I have been developing different packages to analyze DNA methylation. In
all of them, I have used minfi's class GenomicRatioSet to manage DNA
methylation data, in order to take profit of the features of
RangedSummarizedExperiment.

Although I am very happy with the potential of the class, importing its
definition from minfi, makes me add the package to imports. As minfi has a
high number of dependencies (129 in the current release), my packages end
up having hundreds of dependencies too. This is particularly problematic as
I do not use any of the other functions of minfi.

I am wondering whether it could be possible to move minfi's class (or at
least GenomicRatioSet) to a lighter package, so people developing packages
on DNA methylation could rely on this class without having to import the
whole minfi package and its dependencies.

Thank you very much,
