Problem with getFX
Thanks for the reply. This is the traceback:
> traceback()
6: stop("NROW(x) must match length(order.by)")
5: xts(as.numeric(fr[1:length(fr)%%2 != 1]), as.Date(fr[1:length(fr)%%2 ==
1], "%m/%d/%Y", origin = "1970-01-01"), src = "oanda", updated =
Sys.time())
4: getSymbols.oanda(Symbols = Currencies, from = from, to = to,
env = env, verbose = verbose, warning = warning, auto.assign =
auto.assign,
...)
3: getFX("EUR/GBP", from = (Sys.Date() - 499), to = Sys.Date())
2: get(getFX("EUR/GBP", from = (Sys.Date() - 499), to = Sys.Date()))
1: xts(get(getFX("EUR/GBP", from = (Sys.Date() - 499), to = Sys.Date())))

Sys.Date seems to exist.
> Sys.Date()
[1] "2010-07-07"
getSymbol works fine for anything but oanda.
Still at a loss there.
Just used exactly the code below and it still works fine for me.
Maybe show the callstack with traceback to see where it failed?
Maybe Sys.Date isn't a date on your machine (I am speculating now)?

Hi,
I was just trying Wolfgang Wu's loop to load long histories of FX from oanda,
but get the following error message.
Fehler in xts(as.numeric(fr[1:length(fr)%%2 != 1]), as.Date(fr[1:length(fr)%%2
== :
NROW(x) must match length(order.by)
Zus?tzlich: Warnmeldungen:
1: In readLines(tmp) :
unvollst?ndige letzte Zeile in
'C:\DOKUME~1\Owe\LOKALE~1\Temp\RtmpxZe1Dw\file5f906952' gefunden
2: In xts(as.numeric(fr[1:length(fr)%%2 != 1]), as.Date(fr[1:length(fr)%%2 == :
NAs durch Umwandlung erzeugt
Has anybody an idea what went wrong?
library(xts)
library(quantmod)
EURGBP<- xts(get(getFX('EUR/GBP', from = (Sys.Date() - 499), to = Sys.Date())))
for (iDate in seq(500, 2000, by=500)){
EURGBP<- rbind.xts(EURGBP, get(getFX('EUR/GBP', from = Sys.Date() - iDate -
499, to = Sys.Date() - iDate)))
}
colnames(EURGBP)<- "Close";
chartSeries(EURGBP)
