R: Older versions of solar location estimation
old.metropolis R Documentation
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.
