Supplying NA or Zeros in dataframe for missing factor combinations
...binations?
Is there a way to use unstack or do I have to create the combinations
first and then search for each combination within the dataframe and
use rbind to add a row with the missing combination and a value of NA
or 0?
Thanks,
karsten

How to build R on Mac to keep packages running?
...e runs like a charm now, but when I want to start my R.app, it does not start. Only my R64.app is starting, but not all packages are running with R64.app.
Where can I find the magic configure-charms used to configure and build R for the Mac platform?
Yours,
Karsten
