      I haven't seen a reply to this, so I will offer a comment.  
Consider the following: 

qlpm <- RSiteSearch.function('QLPM')

      This identified the frontierPoints function in the fPortfolio 
package.  Beyond this, Wuertz, et al. (2009) Portfolio Optimization with 
R/Rmetrics (www.rmetrics.org/ebook.htm) includes "QLMP" twice and 
"frontierPoints" 55 times. 

      Hope this helps.
