Format a ts_tree object for printing.

Usage

# S3 method for class 'ts_tree'
format(x, n = 10, ...)

Arguments

x

ts_tree object.

n

Number of lines, or number of selections to print.

...

Currently ignored.

Value

Character vector of lines to print.

Details

This is the engine of print.ts_tree(), possibly useful to obtain a printed representation without doing the actual printing.

If there are selected nodes in the tree, those will be highlighted in the output. See ts_tree_select() to select nodes in a tree.
