cumulative

raster* object of continuous (raw) maxent output

<code>scalar</code> value to threshold the continuous map into binary predictions

threshold


The function first converts the raw maxent output to cumulative (by sorting and calculating the cumulative sum).
Then the (optional) threshold is applied to return a binary map of the estimated range.
If <code>threshold</code> is <code>NULL</code>, the cumulative output is returned.


Contains functions to convert binary (presence-absence) expert species range maps (like those found in a field guide) into continuous surfaces based on distance to range edge.  These maps can then be used in species distribution models such as Maximum Entropy (Phillips 2008 <DOI:10.1111/j.0906-7590.2008.5203.x>) using additional information (such as point occurrence data) to refine the expert map.

cumulative: Make maxent's cumulative output from raw output and (optionally) apply a threshold
