Hi Sebastian, here are examples with ggplot2 and basic graphic.

An example: getSymbols("AAPL", src = "yahoo", from = as.Date("2013-07-01"), to = as.Date("2016-06-30")) getSymbols("YHOO", src = "yahoo", from = as.Date("2013-07-01"), to = as.Date("2016-06-30")) getSymbols("CPHD", src = "yahoo", from = as.Date("2013-07-01"), to = as.Date("2016-06-30")) getSymbols("EMC", src = "yahoo", from = as.Date("2013-07-01"), to = as.Date("2016-06-30")) AAPL.xts <- Ad(AAPL) YHOO.xts <- Ad(YHOO) CPHD.xts <- Ad(CPHD) EMC.xts <- Ad(EMC) df <- data.frame(AAPL.xts, YHOO.xts, CPHD.xts, EMC.xts) head(df) library(dygraphs) dygraph(df) -- Best, GG [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
