geom_frequencies: Plot allele frequencies
In MarianaLag/Mlag: Tools Related to the Spatial Analysis of Genetic Marker Data

Description Usage Arguments Value Note Author(s) Examples

This function allows you to plot allele frequencies for several potential levels of stratum and loci.

1	geom_frequencies(x, ...)

`x`	The data frame with allele frequencies from `frequencies`.
`...`	Ingnored but passed on to `facet_grid()` for optional stuff

An object of type ggplot

This function does a pretty good job of plotting but if you have too many loci and/or strata, you may have a difficult time getting it to look right. By default, the function does NOTHING to prevent you from making crappy plots with too many levels. To plot a reduced number of loci/strata, use a subset of your data.
