old.metropolis: Older versions of solar location estimation

In Trackage/tripEstimation: Metropolis Sampler and Supporting Functions for Estimating Animal Movement from Archival Tags and Satellite Fixes

Older versions of solar location estimation

Description

Some deprecated functions, originally used purely for light level estimation before the sampling algorithm was generalized for satellite models as well.

Usage

mkElevationSeg(segments, day)

mkNLPosterior(segments, day, light, calib)

old.dist.gc(x1, x2 = NULL)

old.find.init(mask, nseg, nlpost, pars = c("Lon", "Lat", "k"))

old.metropolis(nlpost, lookup, p0, cov0, start, end, iter = 1000, step = 100)

old.mkLookup(x, binArray = TRUE)

k.prior(seg, ps)

Arguments

segments	vector identifying the segment of each time and light value
day	date-time values in POSIXct

light	vector of light data
calib	calibration function for light levels

x1	matrix of track locations
x2	matrix of track locations (optional second part)

mask	image object of masked areas
nseg	number of (twilight) segments
nlpost	negative log posterior function
pars	names of parameters

lookup	lookup function for masked areas
p0	initial locations for sampler
cov0	covariance matrix for sampler
start	known start parameters
end	known end parameters
iter	number of iterations
step	number of thinning iterations per iter

x	image-like object of matrix or array of binary masks
binArray	logical: are the masks compressed into bits?
seg	segment
ps	light attenuation value

Details

These functions are included for legacy purposes, this was the original implementation.

Value

If it is a LIST, use
