Plot rimmigration flows from many sources to one destination.

PlotImmigrationFlow(data = NULL, source = NULL, destination = NULL,
  n.sources = 5, agg.sources.prefix = "Other ",
  agg.sources.suffix = " sources", cls = NULL, start.degree = 0,
  sources.label.dist = 0.15, sources.label.size = 0.75,
  ticks.label.size = 0.7)

`data`	`data.frame` with sources and destination.
`source`	`data`'s column name or index with places' names. Sources' names and destination's name must be in this column.
`destination`	destination's name.
`n.sources`	number of sources to plot. If smaller than the total number of sources `source`, the less frequent sources are aggregated.
`agg.sources.prefix`	string. If n.sources is smaller than the total number of sources, `agg.sources.prefix` is used to label the aggregated sources.
`agg.sources.suffix`	`character`. If n.sources is smaller than the total number of sources, `agg.sources.prefix` is used to label the aggregated sources.
`cls`	Optional `character` `vector` with `n.sources` + 1 colors.
`start.degree`	The starting degree from which the circle begins to draw. It is passed to the `start.degree` argumento of `circlize::circos.par` function.
`sources.label.dist`	Data point on y-axis to separate the sources' labels from the circle. It is passed to the `y` argument of `circlize::circos.text` function.
`sources.label.size`	Font size for sources' labels. It is passed to the `cex` argument of `circlize::circos.text` function.
`ticks.label.size`	Font size for sources' labels. It is passed to the `labels.cex` argument of `circlize::circos.axis` function.

The numbers arround the circle indicate the number of animals.
