more structure than 'str'?

     How can I see more of the structure than displayed by 'str'?
Consider the following:


tstDF <- data.frame(a=1, row.names='b')

 > str(tstDF)

'data.frame':   1 obs. of  1 variable:
 $ a: num 1


     The object 'tstDF' has row.names, but I have to suspect they are
there -- AND know a function like 'row.names' or 'dimnames' -- to see
them.

     I've found 'str' extremely valuable for understanding and
explaining to others the internal structure of an R object.   In many
cases, it has helped me find fairly simple ways to do things with R
objects that might have been much more difficult and perhaps infeasible
without 'str' -- and without access to the right expert, who may not be
available in the time I have to solve a particular problem.

     Thanks again to Martin Maechler, who wrote 'str', and to everyone
else who has replied to questions from me over the years.

Try this:

  

dput(tstDF)
    

structure(list(a = 1), .Names = "a", row.names = "b", class = "data.frame")
