Many Thanks - Also for the link! It works nice! If i have further question, can i post them here or should i open a new thread?
1) If i want the following to make a function: I do have to convert it, but i canĀ“t get rid of these " " (brackets). func<-function(y) { library(quantmod) getSymbols("y",from="2011-11-01") chartSeries(y) } func(MSFT) 2) How i can get rid of the time dates and get a simple vector?
