[Biomod-commits] correction on projection + oncoming update

Hello Biomoders,

I have lately been informed of a recent bug in the Projection function that I updated lately.

The problem was that the projections when being transformed into binary and filtered values
were being mixed up with the name they were assigned to. In other words, good data with bad 
names. This is what it lead to :

        name     :   'BinRoc',  'BinKappa',  'BinTSS',     'FiltRoc',      'FiltKappa',  'FiltTSS'
        data       :   BinRoc,    FiltRoc,      BinKappa,   FiltKappa,   BinTSS,      FiltTSS

So for example, the FiltRoc data was mistakenly created and stored as the BinKappa. As you
can see BinRoc and FiltTSS were safe !

This only concerns the projection function as it was available on r-forge since the 8th of march.

Hoping it wasn't too much trouble. I would suggest to be carefull with the ensemble forecasts it could
have led to as it would certainly mix things up in there too. One way to sort this out if you don't want to
re-run everything is to rearrange the name, being carefull with that. Off course, it doesn't concern the 
projections in probabilities, nore the ensemble forecast based on probabilities.

The problem is now corrected and has been updated on r-forge today.

Important update : A version of the projection function to be used directly on rasters is soon to be 
available (by the end of the week). The next steps on rasters (Ensemble.Forecasting, Biomod.RangeSize)
will follow rapidly.

Sorry again for the trouble caused.
