checkRates: Evaluate whether potential curve parameters are feasible...

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

Description

Note that parallelization is supported to expedite evaluation; see examples

Usage

checkRates(rdist, dists = NULL, prob = seq(0.1, 1, len = 10),
  rate = exp(seq(log(0.01), log(10), len = 10)), skew = c(0.2), shift = 0,
  verbose = T, plot = T)

Arguments

rdist	raster* object of distances to the range edge (output from rangeDist
dists	frequency table of unique distance values (output from running freq on the rdist object). If NULL, it will be created within the function but can also be supplied here to speed up processing multiple logistic parameters
prob	vector of "probability inside" values to consider
rate	vector of rate values to consider
skew	vector of skew values to consider
shift	vector of shift values to consider
verbose	logical indicating whether to print verbose messages
plot	logical indicating whether to draw a plot of desired probability vs. decay rate.

Value

dataframe of fitted parameters for each parameter combination provided with prob, rate, skew, and shift.

Examples

data(Beamys_hindei_range)
# Generate domain
 domain=raster::raster(xmn=-180, xmx=180, ymn=-90, ymx=90,
 crs="+proj=longlat +ellps=WGS84 +towgs84=0,0,0,0,0,0,0 +no_defs",
 resolution=.1, vals=NULL)
 # registerDoParallel(2) #optionally use to speed up calculation
 # Calculate distance to range
 rdist=rangeDist(range=Beamys_hindei_range,domain=domain,
                 domainkm=1000,mask=FALSE,fact=2,verbose=FALSE)
 dpar=checkRates(rdist,plot=FALSE)
