plot_tree: Plot the monoClust Tree.
In monoClust: Perform Monothetic Clustering with Extensions to Circular Data

This function plots the MonoClust tree. It is partially inspired by rpart package.

plot_tree(
  x,
  uniform = FALSE,
  branch = 1,
  margin = 0,
  minbranch = 0.3,
  rel.loc.x = TRUE,
  ...
)

`x`	MonoClust result object.
`uniform`	If TRUE, uniform vertical spacing of the nodes is used; this may be less cluttered when fitting a large plot onto a page. The default is to use a non-uniform spacing proportional to the inertia in the fit.
`branch`	Controls the shape of the branches from parent to child node. Any number from 0 to 1 is allowed. A value of 1 gives square shouldered branches, a value of 0 give V shaped branches, with other values being intermediate.
`margin`	An extra fraction of white space to leave around the borders of the tree. (Long labels sometimes get cut off by the default computation).
`minbranch`	Set the minimum length for a branch to `minbranch` times the average branch length. This parameter is ignored if `uniform = TRUE`. Sometimes a split will give very little improvement, or even no improvement at all. A tree with branch lengths strictly proportional to improvement leaves no room to squeeze in node labels.
`rel.loc.x`	Whether to use the relative distance between clusters as x coordinate of the leaves. Default is TRUE.
`...`	Arguments to be passed to `graphics::plot.default()` and `graphics::lines()`.
