Have a look at the AnnotatedDataFrame class in the Biobase package [1]. Here is the description from the manual:
An ‘AnnotatedDataFrame’ consists of two parts. There is a collection of samples and the values of variables measured on those samples. There is also a description of each variable measured. The components of an ‘AnnotatedDataFrame’ can be accessed with ‘pData’ and ‘varMetadata’. Hope this helps, Laurent [1] http://bioconductor.org/packages/release/bioc/html/Biobase.html On 22 June 2011 15:57, Robert Lundqvist <robert.lundqv...@nll.se> wrote: > Every now and then I realize that my attempts to document what all dataframes > consist of are unsufficient.
