Creates an Evanno plot from a STRUCTURE run object

This function takes a genlight object and runs a STRUCTURE analysis based on functions from strataG

Usage

gl.evanno(sr, plot.out = TRUE)

Arguments

sr: structure run object from gl.run.structure [required].
plot.out: TRUE: all four plots are shown. FALSE: all four plots are returned as a ggplot but not shown [default TRUE].

Value

An Evanno plot is created and a list of all four plots is returned.

Details

The function is basically a convenient wrapper around the beautiful strataG function evanno (Archer et al. 2016). For a detailed description please refer to this package (see references below).

Examples

if (FALSE) {
#CLUMPP and STRUCTURE need to be installed to be able to run the example
#bc <- bandicoot.gl[,1:100]
#sr <- gl.run.structure(bc, k.range = 2:5, num.k.rep = 3, exec = './structure.exe')
#ev <- gl.evanno(sr)
#ev
#qmat <- gl.plot.structure(sr, k=3, CLUMPP='d:/structure/')
#head(qmat)
#gl.map.structure(qmat, bc, scalex=1, scaley=0.5)
