There's no reason to create multiple xts objects if you intend to
merge them all into one object. You say the user can select
timeseries, so I assume you have column names in a vector. If so, you
can do something like this:
series <- c("M", "G", "N")
...
zonnen <- xts(df[,series], as.POSIXct(df$
Thanks Paul,
I'm just a beginner with R, so I tried your simplest solution ( zonnen
<- xts( cbind( ... ) and it seems to work fine.
cheers,
Stef

There is a utility function TSquery() in package TSsql that attempts to
do this. Most of the functions in that package are for databases with a
specific layout intended for storing time series, but TSquery() attempts
to build a series from a somewhat arbitrary database. It is hard to be

hello,
I've a number of timeseries into a database and want to display these
timeseries into graph.
Now the code below works well, but as the user can select which
timeseries should be shown (up to 20 timeseries) the code below should
be dynamic and can be quiet large and complex.
Is there
