Clicking on the name "definitions" as opposed to the icon to expand the entry opens the "definitions" data frame in its own tab in a pane on the upper left where files such as scripts are displayed. Clicking that tab opens the list of "definitions" which is a list of three entries, where the variable ids from the "mydata" file are row names. That will be the case in any session accessed using RStudio and opening your saved .RData file. If you are concerned about non-RStudio users being able to access that data.frame in the Windows version R, if they load the .RData file that will load the "definitions" data frame, which can be listed simply typing "definitions" at the command prompt. There is no "right way" do this. Your approach works, though it will get awkward if the data frame contains very many definitions. If you look at SPSS (or PSPP) for instance the Data Name and Label are both elements of the definition of the variable, and the Label element of the SPSS variable definition is essentially what your example seems to use as a definition. Otherwise you seem to be treading around the edges of metadata which is also a set of data definitions. R is more flexible about these things, which makes it somewhat more of a chore at times. ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
