Edit: Thank you, the solution with dplyr works great for all my categorical variables. Next, I've tried to change the colour argument in ggplot, (also tried as in geom_line), but that way, I don't have 20 lines anymore. So in this example, instead of three lines, the average values per occasion for the two males would form one line, the points for female a second line.
Now, I'm trying to figure out how I can distinguish between subgroups by colouring their lines based on a second/third factor.

Phone sex is a great way to spice up your sex life, whether you're doing it because your partner is far away, because you're not ready to have other kinds of sex together yet, because you just want to try something new, or any other reason!Here are a few examples of the heterosexual age of consent in different countries: Essentially it means that if you have sex with someone when you or they are under the age of consent, then you are breaking the law – even if you both have sex willingly.In the eyes of the law people are unable to give informed consent to sex when they are still considered a child. Luckily for us nosy types-and those who have a purely academic curiosity about the sordid details of other people's sex lives-AARP has released the official findings of its 2009 Sex, Romance, and Relationships Survey. That depends on what's going on in your bedroom-and how your love life stacks up against the "norm." A clue: If you're a woman in your 50s and you have sex at least once a week, 64 percent of your peers might be jealous. These probably aren't questions you'd relish answering, at least not in front of the kids.I also get vertical lines for each measurement occasion. The only way I cold imagine fixing this is to create a new variable average.motivation and to compute the average for every group per occasion and then assign this average to all members of the group.
