Hi Vince, The following works for me: library(its) x <- priceIts(instrument="INTC", start="2005-01-01", quote="Close") names(x) <- "Close" x <- data.frame(core(x)) str(x) `data.frame': 59 obs. of 1 variable: $ Close: num 23.1 22.6 22.4 22.5 22.8 ... 'core()' is one of those 'hidden' functions I got from Dirk. Hope that helps, jab -- John Bollinger, CFA, CMT www.BollingerBands.com If you advance far enough, you arrive at the beginning.
