[Biomod-commits] New with BIOMOD; how can I predict my species distributions in another region?

I am trying to learn BIOMOD by using the sample Sp.Data and by following the instructions in BIOMOD Tutorial, 2012.
What interests me is to predict species distributions in other regions or under climate change scenarios. Unfortunately, I have not really understood what is the procedure to follow; I am afraid that the tutorial can be very confusing for non experts in SDM... Here are my questions:
1) How can I obtain info about the predictive performance of a model on my already known localities? There are three functions, Models(), CurrentPred() and PredictionBestModel(), whose differences I find hard to understand.
2) Under what criterion can someone chose the best model for new datasets (e.g. other regions or climate change scenarios)? Is the best model for my dataset also the best for a new dataset?
3) What is the difference between Projections() and Ensemble.Forecasting()? Which of these two functions is suitable for predicting the species' presence in another region?
4) I have information about my species' presence but not for their absence. Does this still mean that I have to create a presence-absence table and then use pseudo-absences?
