Hi there!
I'm stuck with a problem aligning financial timeseries and haven't found
a cue how to fix it...
When I run that simple script, everything goes well until the
"align"-command:
------
rm(list=ls())
x <- yahooSeries("^GDAXI")
head(x)
xAligned <- align(x = x, by = "1d", method = "before", include.weekends
= FALSE)
------
Here's the command-line dialog:
------
> rm(list=ls())
> x <- yahooSeries("^GDAXI")
versuche URL
'http://chart.yahoo.com/table.csv?s=^GDAXI&a=&b=&c=&d=8&e=07&f=2009&g=d&x=.csv'

Fehler in seq.default(u[1] + offset, u[length(u)], by = by) :
wrong sign in 'by' argument
-----
Besides, Example-Data (SWX) from the "fPortfolio"-package is aligned
nicely by exactly the same command. Does anybody have an idea what the
problem could be? I'm grateful for any help!
Kind regards,
Gero
