[QuantMod] Load all stock symbols

Hello everybody,

I was wondering how to load all the symbols at once using Quantmod.

I am trying to load them, so I will be able to test a set of parameters 
for each one.

For example, if the S&P where to have only 3 symbols, I could just write 
this...
 > getSymbols("KO;PEP;SBUX")
 > test(KO)
 > test(PEP)
 > test(SBUX)

but, how can I try this over all the S&P?
btw, test is a made-up function to illustrate the idea.

Thanks you
Jeff Ryan

Just extend the logic you have.

A full list of S&P symbols can be found via google (current and
historical), and you can just create a semi-colon delimited string to
pass into the function.

The function will pause 1s between requests after 5 symbols in one
call, so as to be kind to the Yahoo servers.  Left as a user exercise
if you are bent on bypassing.

HTH
Jeff

Assume you have all the stock tickers...

            

      
      
      
    

        
[1] "KO;PEP;SBUX"

            

      
      
      
    

        
[1] "KO"   "PEP"  "SBUX"

            

      
      
      
    

        
[1] "KO"   "PEP"  "SBUX"

            

      
      
      
    

        
+ mean(get(x))
+ }

            

      
      
      
    

        
[[1]]
[1] 1850594

Hope it helps,
