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()

Many Thanks - Also for the link!
It works nice!
Alas the passing of the adverb. We loved her well. She will be missed.
If i have further question, can i post them here or should i open a
new
thread?
Please do not extend threads beyond the topics reasonably covered by
their subject lines.
(And DO read the Posting Guide where this and many other questions
have been addressed.)
1)
If i want the following to make a function:
I do have to convert it, but i can´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?
?xts
As you read the help pages, (you do read help pages, plural, right?)
you should have found that coredata() returns the "interior" of xts
objects. index() and coredata() are described on the first reference
from help(xts) to package zoo (which doesn't have a working hyperlink
on my current version) so go to ....
?zoo
# one is expected to follow references from help pages ....as well as
read all of the pages.
