par.secr.fit: Fit Multiple SECR Models

Description

These functions are wrappers for secr.fit, region.N and derived that allow multiple models to be fitted simultaneously on multi-core machines.

Usage

par.secr.fit (arglist, ncores = 1, seed = 123, trace = TRUE, logfile = "logfile.txt")
par.derived (secrlist, ncores = 1, ...)
par.region.N (secrlist, ncores = 1, ...)

Arguments

arglist

list of argument lists for secr.fit or a character vector naming such lists

ncores

integer number of cores to be used for parallel processing

seed

integer pseudorandom number seed

trace

logical; if TRUE intermediate output may be logged

logfile

character name of file to log progress reports

...

other arguments passed to derived or region.N

secrlist

secrlist object

Value

• For par.secr.fit - secrlist of model fits (see secr.fit). Names are created by prefixing ``fit.'' to the names of argslist. If trace is TRUE then the total execution time and finish time are displayed. For par.derived - a list of dataframes output from derived, applied to each model in turn. For par.region.N - a list of dataframes output from region.N, applied to each model in turn.

Details

Any attempt in arglist to set ncores > 1 for a particular secr fit is ignored. trace overrides any settings in arglist. Reporting of intermediate results is unreliable on Windows when ncores > 1. It is convenient to provide the names of the capthist and mask arguments in each component of arglist as character values; objects thus named are exported from the workspace to each worker process (see Examples).
