Get the sequence of complexity parameters of an SDTree

Source: R/get_cp_seq.R

This function extracts the sequence of complexity parameters of an SDTree that result in changes of the tree structure if pruned. Only cp values that differ in the first three digits after the decimal point are returned.

# S3 method for class 'SDTree'

set.seed(1)
n <- 10
X <- matrix(rnorm(n * 5), nrow = n)
y <- sign(X[, 1]) * 3 + rnorm(n)
model <- SDTree(x = X, y = y, Q_type = 'no_deconfounding', cp = 0)
get_cp_seq(model)
