d3dendrogram: Plot dendrogram to webpage and view.
Description
Plot dendrogram to webpage and view.
Usage
d3dendrogram(d, height = 500, width = 700, rightmargin = 200, open = TRUE, ...)
Arguments
height
pixels, height of the plot.
width
pixels, width of the plot
rightmargin
pixels to reserve on the right side for leaf labels.
open
open the graphic in a browser? (see details).
Value
If open=TRUE, a character string containing the html is invisibly retured.
If open=TRUE, a character string containing the html is returned.
Tips
Dendrogram plots with many end-nodes tend to get overlapping labels or (end)nodes. If the number of endnodes
is not too large, there are several ways to overcome this.
- Decrease font size of the nodes (
node_font, see d3dendro_options on how to specify)
- Decrease size of node radius (
node_radius, idem)
- Increase the height of the plot. Use about (2 times font height) times count_terminal_nodes(d).
- Plot sub-dendrograms in stead of the whole dendrogram. There's only so much
detail a screen can display and your eye can observe. Consider plotting subdendrograms or other summaries
when dendrograms have many, many nodes.
Details
If open=TRUE, the graphic is opened using the function defined by getOption("viewer").
If no viewer option is specified, utils::browseURL is opened. Specifically, in RStudio
this means that the viewer is used.
