[Bioc-devel] include .DollarNames.ExpressionSet in Biobase?

Hi Phillip --

es$foo accesses phenoData(es)$foo, so I implemented .DollarNames.eSet for this.

An ExpressionSet is rectangular and has two-dimensional subsettings, the core data is a matrix, and generally ExperessionSet behaves like a matrix. So rather than names() try colnames().

Thanks for the suggestion.

the S3 generic .DollarNames is used to create tab completions in the R command
line and RStudio.

since you can access featureData(es)$feature via es$feature, it would be
useful to either implement .DollarNames.ExpressionSet or simply

I couldn’t find a bug tracker for BioConductor, so i posted this here.
