compress

rtrans

unrtrans

<code>character</code> path to file to be compressed

file

Function to use to compress the data.  Default is <code>rtrans()</code>, which is <code>round(log(x)*100</code>.

value passed to <code>rtrans</code> or <code>untrans</code> for conversion.

additional functions to be passed to <code>writeRaster()</code>


Maxent writes out ASCII files that are uncompressed. This function transforms the data, converts it to a compressed
geotif, and deletes the original.  The default transform <code>rtrans</code> is to take the $round(log(x)*100)$.
Note that this conversion may be lossy depending on the transform applied.


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.
