1) It's sort of a cheap trick, but this works flexibly (i.e., you can
put in func(SPY) or func("SPY") and get the same output):
func <- function(y){
if(!require(quantmod)) stop("You need the quantmod package.")
chartSeries(get(getSymbols(as.character(substitute(y)), from =
"2011-11-01")))
}
2) coredata()
