Description Details Author(s) References

Detect population structure (i.e sub-populations), making use of genetic (and optionally geographic) information.

The main purpose of the program is to perform Bayesian inference of all the parameters involved
through Markov Chain Monte-Carlo simulation.
This is achievied by the function `MCMC`

.
Function `PostProcessChain`

read some output files of
`MCMC`

and computes some statistics suitable to print maps of inferred
populations.

See `Storage format`

section in `MCMC help page.`

The following functions are provided by the package:

`simFmodel`

: simulation from the prior of the spatial
F-model

`simdata`

: Simulation of georeferenced genotypes under an IBD + barrier
model

`show.simdata`

: Graphical display of data simulated by simdata

`MCMC`

: Full Bayesian Markov Chain Monte Carlo
inference of parameters in the spatial F-model

`PostProcessChain`

: Post-procesing of MCMC output
for maps of posterior probability of populations subdomains

`PlotTessellation`

: Graphical display of inferred
sub-domains

The following functions are very basic and are only intended to be an
aid for those not familiar with R. Most probably you may want to use
directly the output files of `MCMC`

and
`PostProcessChain`

to print your own figures.

`PlotDrift`

: Graphical display of drift factors along MCMC
run

`PlotFreqA`

: Graphical display of allele frequencies in the
ancestral population along MCMC run

`PlotFreq`

: Graphical display of allele frequencies in the
present time population along MCMC run

`Plotnpop`

: Graphical display of number of populations
along MCMC run
