PlotFreq: Plot the trace of allele frequencies in present time...
In Geneland: Detection of Structure from Multilocus Genetic Data

Plot of allele frequencies in present time populations number ipop, for allele iall of locus iloc

1	PlotFreq(path.mcmc,ipop,iloc,iall,printit=FALSE,path)

`path.mcmc`	Path to output files directory
`ipop`	Integer number : index of population
`iloc`	Integer number : index of locus
`iall`	Integer number : index of allele. If `MCMC` was launched with option `filter.null.alleles=TRUE`, an extra fictive allele standing for putative null alleles is created. It estimated frequency can be also plotted. If there is say, 5 alleles at a locus, the estimated frequency of null alleles can be seen invoking `PlotFreq` with `iall=6`.
`printit`	Logical : if TRUE, figures are also printed
`path`	Character : Path to directory where figures should be printed
