so then the above with 4 symbols works fine, but when you add a symbol

library(quantmod) 

sym1 <- "SPY" 
sym2 <- "ILF" 
sym3 <- "EWZ" 
sym4 <- "DIA"  
sym5 <- "EPP"
initDate <- "2010-01-01" 
getSymbols(sym1,from=initDate) 
getSymbols(sym2,from=initDate) 
getSymbols(sym3,from=initDate) 
getSymbols(sym4,from=initDate) 
getSymbols(sym5,from=initDate) 

df <- data.frame( dailyReturn(get(sym1)), dailyReturn(get(sym2)), 
                  dailyReturn(get(sym3)), dailyReturn(get(sym4)),
			dailyReturn(get(sym5))) 
names(df) <- c(sym1,sym2,sym3,sym4,sym5) 
print(round(cor(df),2))





you get an error message.  what am i missing?
