Dear Developers, after several discussions on r-help I got the impression that the "standard" R distribution, including the recommended packages, does not offer much to document raw data, imported into R. Hmisc has some functionality in this respect, and others like Richard Heiberger solved some other aspects, but I think there could be a more unified approach, which, of course needs the support from the core developers to become "standard". In particular I am looking for is a possibility to label variables, label values and add other information. Of course, all this is possible by adding attributes, but most attributes are lost when indexing/subsetting.>From many helpful suggestions of others I learned that this can be resolvedby defining a class and corresponding methods, as is done for variable labels in Hmisc. For now I drafted something more general for my personal use, but before continuing on this I want to know, if there is some intention at the core developer team to work on the question of raw data documentation. Greetings, Heinz T?chler
