Description Usage Arguments Details Value References See Also
Following the approach of
\insertCiteevanssmith2009;textualphyloclim, pno
integrates
species probability (suitability) distributions (e.g. derived with MAXENT)
with respect to single climatic (or other environmental) variable in order
to get predicted niche occupancy (PNO) profiles for each species and
environmental variable.
1 |
path_bioclim |
A character string, giving the path to an ASCII raster map with environmental data (bioclimatic layer) and ArcGIS-compatible header (see Details). |
path_model |
A character string, giving the path to the directory, where MAXENT probability surfaces are stored as ASCII raster maps with ArcGIS-compatible header (see Details). |
subset |
A vector of mode 'character' giving taxon names if only a
subset of the species ENMs in |
bin_width |
A numeric, giving the bin interval. |
bin_number |
An integer, giving the number of bins used. |
The path argument path_model
points to the directory where
the MAXENT probability distributions must be stored as ASCII maps with an
ArcGIS-compatible header (as obtained with MAXENT output filetype:
asc).
An example for an ArcGIS-compatible header:
ncols | 958 | |
nrows | 376 | |
xllcorner | -73.440304 | |
yllcorner | -55.27622 | |
cellsize | 0.0166 | |
NODATA_value | -9999 | |
A data frame of cumulative probalities of suitability for each value on an environmental gradient (rows) for the a set of studied taxa (rows). The first column gives the mean of each category.
