[R] Problem in downloading Yahoo Finance data from R

[Theta]

Hello Shubha,

alternative method that gets closing prices of the SP500 Index, last line 
calculates the logreturns, easy to use data.

sp500 <- get.hist.quote("^GSPC",start=(today <- Sys.Date())-735,quote="Cl")
rsp500 <- diff(log(sp500))
