I'm basiclly completly new to R, but I'm required to use it for a paper I'm writing at. So far I was able to get the basics like, summary and getting the overall arihmetic means and so on. My Problem now is, That I basiclly have two factor of Data that I aquired
One is the kind of Data (One is the Estaury of the bird species I'm writing about, the other is Control Plots. Than this two are divided into a South and Noth Area. So now I need to compare North, South and Control Plots and estuarys. So for example I want the mean of all Northern estuarys and than off all Southern control plots. I don't really get around how to do this, I was thinking about with a data frame maybe?
Thanks for your Help in forward
