Maybe I used the wrong words, but It is no homework but an empirical research. Nevertheless thanks for your help.

Now I have the years on the vertical axes and on the horizontal axes R&D expenditure per country (R&D germany, R&D france etc), I did this also for the unit labor costs. Or is it easier to put all the R&D expenditure in one column and make another column for the country? Do I have to make the dummy variable in my database or can I use Stata for creating this?
