plotTreeBar: Generate a barplot of a Structure or Admixture run.
In sa-lee/starmie: Population Structure Model Inference and Visualisation

Generate a barplot of a Structure or Admixture run.

1	plotTreeBar(x, facet = TRUE, dendro = NULL, cut = NULL)

`x`	a single cluster run object of type `struct` or `admix` or Q-matrix
`facet`	whether or not to split the barplot by cluster. This is recommended.
`dendro`	an object of class 'hclust' (defaults to hclust with average linkage)
`cut`	an integer vector output by 'cutree' (defaults to cutree k=ncols(Q))

# Read file using K = 6 and plot results
k6_data <- exampleStructure("barplot")
# our facetted structure plot with tree
plotTreeBar(k6_data)
# standard 'structure' bar plot with tree
plotTreeBar(k6_data, facet = FALSE)
# Admix example
k3_data <- exampleAdmixture()[[3]]
plotTreeBar(k3_data)
