- branch_nodes
An integer vector, specifying the nodes to keep.
- include_lower
A logical value - whether or not the lower branches should
also be kept.
Examples
ex1 <- quote(x <- f(y, g(5)))
th1 <- TreeHarp(ex1, TRUE)
keep_branches(th1, 3)
#>
keep_branches(th1, 3, include_lower = FALSE)
#>
keep_branches(th1, c(2,3), FALSE)
