It's not very difficult to write a function that lists your objects in
a dataframe along with the sort of information you'd like to see.  I
personally like to know the size of dataframes so it was simple to
make columns that shows the dimensions.  It was somewhat trickier to
get the date but I like to have it, so I did it.  

My current directory has things like this in it:

      Object        Mode   Rows Cols Len    Date   
1 fmr.pvh2000    function  --    --   1  12/07/2002
2 last.warning   list      --    --   5  12/07/2002
3 pvh.latto2000  function  --    --   1  09/07/2002
4 pvh.latto2000A function  --    --   1  09/07/2002
5 rain.plot2000  function  --    --   1  09/07/2002
6 accum2000      function  --    --   1  04/07/2002
7 pvh.latto4     function  --    --   1  04/07/2002
8 side.df        dataframe 1000  5    5  04/07/2002

I wrote my function some years ago and could do it much better knowing
what I know now, but if someone wants to make something generally
available, mine might be a good starting point.
