Please try to post *minimal* reproducible examples. Only two packages
are needed to run your code.
library(quantmod)
library(tseries)
symbols<-getSymbols(c("^GSPC", "^DJI"))
endDate <- Sys.Date()
startDate <- endDate - as.difftime(52*5, unit="weeks")
quoteType <- "Close"
p <- do.call(cbind, lapply(symbols, get.hist.quote,
start=startDate, end=endDate, quote=quoteType))
Your calls with get.hist.quote() are not what you expect. Note that
the tickers you passed to getSymbols() are "^GSPC" and
"^DJI". But
those are not the objects that getSymbols() creates (or the adjusted
ticker symbols it returns), because they are not syntatically valid R
names (because they start with a circumflex).
So you call get.hist.quote() with tickers "GSPC" and "DJI",
which are
not the S&P 500 and Dow Jones Industrial indexes, respectively. The
GSPC data is not what you expect, and there's no data for DJI.
