I'm avare that I'm trying to plot factors and numeric in the same try. What I needed confirmed, before waisting more time seeking the answer, was if this was possible. Now I have confirmed that this is in deed not possible.
I have received a really good answer on stackexchange, which I like to share with the list: http://stackoverflow.com/questions/15999304/plotting-continuous-and-discrete-series-in-ggplot-with-facet Regard, Sigurgeir 2013/4/14 Dennis Murphy <djmu...@gmail.com> > Look at head(mcsm): > > > head(mcsm) > date variable value > 1 1967-06-30 q Q2 > 2 1967-07-31 q Q3 > 3 1967-08-31 q Q3 > 4 1967-09-30 q Q3 > 5 1967-10-31 q Q4 > 6 1967-11-30 q Q4 > > I suspect what you're trying to do and it won't work the way you're > doing it.
