Dear Users, I have two particular problems that I need to solve. I do an analysis of a survey about sexuality. (Don't read any further if you don't like the subject.) Problem (1) In the survey there a two questions about monogamy. (1) Are you monogamous? (At this moment.) (2) Have you been in contact with men and / or women? (Past / Present) For some other inferences I need to extract historical data out of these questions about monogamy, like past monogamy (which hasn't been asked). This should be possible. Is there a reasonable way out of here? Problem (2) I have to do some geographical testing. I have to check the geographical distribution of respondents and some other properties. Could you advise me what to read / use? An R package with help is sufficient (I hope). Thanks, Wilfred
