Render an expert-system hierarchy and open it in a browser

Builds the self-contained HTML tree (see resy_write_expert_html) in a temporary file and opens it in the default browser. Use resy_write_expert_html directly to keep the file.

Usage

resy_view_expert(
  expert,
  section = 3L,
  fill = TRUE,
  open_level = 1L,
  title = NULL,
  names = NULL,
  name_tag = NULL,
  browse = interactive()
)

Arguments

expert

Either a resy_expert object (from resy_read_expert) or a resy_expert_tree (from resy_expert_tree).

section

Integer; the definition section to use when expert is a resy_expert. Defaults to 3. Ignored for a resy_expert_tree.

fill

Logical; reconstruct the intermediate group levels (see resy_expert_tree). Defaults to TRUE for the view, so the page shows a single tree rooted in the formation groups. Ignored for a resy_expert_tree, which is already built.

open_level

Integer; nodes at this level or shallower start expanded. Defaults to 1 (the top groups are open, their contents collapsed).

title

Page title; defaults to the section name.

names

Optional code-to-name lookup for nodes the expert leaves unnamed (see resy_expert_tree); pass resy_eunis_names for EUNIS. Ignored for a resy_expert_tree, which is already built.

name_tag

Optional short label shown beside names supplied through names (for example "EUNIS"), to mark them apart from the expert's own descriptions. Defaults to NULL (no tag).

browse

Logical; open the file in a browser. Defaults to interactive().

Value

The path to the written HTML file, invisibly.
