textLongCART: Place text on LongCART tree

In LongCART: Recursive Partitioning for Longitudinal Profiles

Description

Labels the current plot of the tree generated from LongCART object with text.

Usage

textLongCART(x, splits = TRUE, all = FALSE, 
             use.n = FALSE, minlength = 1L, ...)

Arguments

x	a fitted object of class "LongCART", containing a linear mixed effects tree.
splits	similar to plot.rpart; logical flag. If TRUE (default), then the splits in the tree are labeled with the criterion for the split.
all	Logical. If TRUE, all nodes are labeled, otherwise just terminal nodes.
use.n	Logical. If TRUE, adds n to label.
minlength	the length to use for factor labels. A value of 1 causes them to be printed as 'a', 'b', ..... Larger values use abbreviations of the label names. See the labels.rpart function for details.
...	arguments to be passed to or from other methods.
