What you are looking for is in the rmetrics/fPortfolioAdvanced package.  
Look for the function called "feasibleSet".  A chart
similar to what you want would be generated by this

   >data = 100*LPP2005.RET[, 1:6]
   >set = feasibleSet(data)
   >attributes(set)
$names
[1] "data"          "weights"       "coords"        "positions" 
"targetReturns"
[6] "targetRisks"   "hull"

The weights of the portfolios in the set would be found in set$weights

Two other functions in that package may also help ...

Regards,
Matt
