[R-SIG-Finance] Q re: running the Workshop 2010 script

[matt at considine.net]

I suspect I am overlooking something pretty straightforward, but for  
the life of me can't figure out what it is.  Apologies in advance if  
the answer should be obvious to me...

I am trying to run the 2010 Workshop script found here :
    
https://r-forge.r-project.org/scm/viewvc.php/pkg/PortfolioAnalytics/sandbox/script.workshop2010.R?view=markup&revision=1673&root=returnanalytics

but am getting this error as I step through it :
> table = as.matrix(ES(indexes[,1:4], weights=rep(1/4,4),  
> portfolio_method="component", p=(1-1/12))$pct_contrib_MES)

Error in ES(indexes[, 1:4], weights = rep(1/4, 4), portfolio_method =  
"component",  :
   could not find function "operES.CornishFisher.portfolio"

Now, I understand what that means.  Thinking that I was using a  
too-recent version of the code, I checked out and installed rev 1844  
(as an example), but got the same error.  When I look at the NAMESPACE  
file, I see that this is supposed to be an un-exported function.

My question is - how do I get this function recognized?  I really  
doubt it involves tinkering with the code itself, so I'm thinking that  
I have overlooked something pretty straightforward in my invoking
   library(PerformanceAnalytics)
   library(PortfolioAnalytics)

I am running R 2.14.2 on Windows (and dealing with doSNOW rather than  
doMC, though that's not relevant on this issue) and sessionInfo is  
below my sig.

I realize that the authors have a lot to do with this year's workshop,  
so any help - and patience in replying - would be greatly appreciated.

Regards,
Matt
