title: How to find list of attached data-sets in R?
body: <p>Is there any method in <code>R</code> to find out what data-sets have been attached.  In my work flow i use the console and build a script.  I try out the lines of code in console and once i am satisfied with the results, i add them to a script so that I can reproduce the results later.  For past week i have been playing with a few data-sets.  I think I attached and detached a number of them over time.  But now I need to know what data-sets are current attached, so that I can detach them.</p>
