compress: Compress maxent output by converting from ASCII file to...

In bossMaps: Convert Binary Species Range Maps into Continuous Surfaces Based on Distance to Range Edge

Description

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 rtrans is to take the round(log(x)*100). Note that this conversion may be lossy depending on the transform applied.

Usage

compress(file, fun = rtrans)

rtrans(x)

unrtrans(x)

Arguments

file	character path to file to be compressed
fun	Function to use to compress the data. Default is rtrans(), which is round(log(x)*100.
x	value passed to rtrans or untrans for conversion.
...	additional functions to be passed to writeRaster()

Value

Returns the converted file as a raster() object

Functions

• rtrans: transform data to faciliate storing as an integer as round(log(x)*100).

• unrtrans: uncompress data transformed with rtrans
