Build a data frame

Source: R/fortify-data-frame-dendrogram.R
fortify_data_frame.dendrogram.Rd

[Stable]

This function converts various objects to a data frame.

Usage

# S3 method for class 'dendrogram'
fortify_data_frame(
  data,
  ...,
  priority = "right",
  center = FALSE,
  type = "rectangle",
  leaf_pos = NULL,
  leaf_braches = NULL,
  reorder_branches = TRUE,
  branch_gap = NULL,
  root = NULL,
  double = TRUE,
  data_arg = NULL,
  call = NULL
)

# S3 method for class 'hclust'
fortify_data_frame(data, ...)

Arguments

data

A hclust or a dendrogram object.

...

Additional arguments passed to dendrogram method.

priority

A string of "left" or "right". if we draw from right to left, the left will override the right, so we take the "left" as the priority. If we draw from left to right, the right will override the left, so we take the "right" as priority. This is used by align_dendro() to provide support of facet operation in ggplot2.

center

A boolean value. if TRUE, nodes are plotted centered with respect to all leaves/tips in the branch. Otherwise (default), plot them in the middle of the direct child nodes.

type

A string indicates the plot type, "rectangle" or "triangle".

leaf_pos

The x-coordinates of the leaf node. Must be the same length of the number of observations in tree.

leaf_braches

Branches of the leaf node. Must be the same length of the number of observations in tree. Usually come from cutree.

reorder_branches

A single boolean value, indicates whether reorder the provided leaf_braches based on the actual index.

branch_gap

A single numeric value indicates the gap between different branches.

root

A length one string or numeric indicates the root branch.

double

A single logical value indicating whether horizontal lines should be doubled when segments span multiple branches. If TRUE, the horizontal lines will be repeated for each branch that the segment spans. If FALSE, only one horizontal line will be drawn. This is used by align_dendro() to provide support of facet operation in ggplot2.

data_arg

The argument name for data. Developers can use it to improve messages. Not used by the user.

call

The execution environment where data and other arguments for the method are collected. Developers can use it to improve messages. Not used by the user.

Value

A data frame with the node coordinates:

  • .panel: Similar with panel column, but always give the correct branch for usage of the ggplot facet.

  • .index: the original index in the tree for the the node

  • label: node label text

  • x and y: x-axis and y-axis coordinates for the node

  • branch: which branch the node is. You can use this column to color different groups.

  • panel: which panel the node is, if we split the plot into panel using facet_grid, this column will show which panel the node is from. Note: some nodes may fall outside panel (between two panels), so there are possible NA values in this column.

  • leaf: A logical value indicates whether the node is a leaf.

ggalign attributes

edge: A data frame for edge coordinates:

  • .panel: Similar with panel column, but always give the correct branch for usage of the ggplot facet.

  • x and y: x-axis and y-axis coordinates for the start node of the edge.

  • xend and yend: the x-axis and y-axis coordinates of the terminal node for edge.

  • branch: which branch the edge is. You can use this column to color different groups.

  • panel1 and panel2: The panel1 and panel2 columns have the same functionality as panel, but they are specifically for the edge data and correspond to both nodes of each edge.
