Plots conditional inference trees.

Plots a partykit conditional inference tree in a pretty and simple way.

NiceTreePlot(ct, inner_plots = FALSE, cex = 0.8, justmin = 15)

Arguments

ct

A tree of class constparty (as returned by ctree from partykit package).

inner_plots

Logical. If TRUE, plots are displayed at each inner node. Default is FALSE.

cex

Numerical value. Multiplier applied to fontsize. Default is 0.8.

justmin

Numerical value. Minimum average edge label length to employ justification (see panelfunctions documentation from partykit package)

Examples

  data(iris)
  iris2 = iris
  iris2$Species = factor(iris$Species == "versicolor")
  iris.ct = partykit::ctree(Species ~ ., data = iris2)
  NiceTreePlot(iris.ct, inner_plots = TRUE)
