Add Layer for hierarchical dataframe

Source: R/builder.R

Used in conjunction with add_root() to generate dataframe for use with hp_dataframe().

add_layer(
  .data,
  child_col,
  node_type_col = NULL,
  node_type_vals = " ",
  link_col = NULL,
  link_vals = " ",
  attribute_cols = NULL
)

Arguments

.data

Output from add_root() or add_layer().
child_col

Column to generate children from.
node_type_col, node_type_vals

Column or values to use as node_type. If not specified, all node types will be assigned as blank (" ") for the layer.
link_col, link_vals

Column or values to use as link. If not specified, all links will be assigned as blank (" ") for the layer.
attribute_cols

Column to use for generating attribute labels.

Examples

os_survey %>%
  add_root("OS Students 2014/15") %>%
  add_layer(
    child_col = "Operating System",
    link_vals = "OS",
    node_type_vals = "OS"
  ) %>%
  add_layer(
    child_col = "OS Version",
    link_vals = "Ver",
    node_type_vals = "Sub",
    attribute_cols = "users"
  ) %>%
  hp_dataframe(
    title = "Survey Results of Most Popular OS in 2014/15",
    styles = hierplane_styles(
      link_to_positions = list(Ver = "right")
    )
  ) %>%
  hierplane()
