ggseg3d: ggseg3d: Plot brain segmentations with plotly

In ggseg3d: Tri-Surface Mesh Plots for Brain Atlases

Description

Plotting results from analyses done on data derived from brain segmentations is a common need, but may be quite laborious. Results from such analyses are usually easier to interpret if the plot can mimmick the shape and position in the brain it represents.

ggseg3d plots and returns a plotly mesh3d object.

Usage

ggseg3d(
  .data = NULL,
  atlas = "dk_3d",
  surface = "LCBC",
  hemisphere = c("right", "subcort"),
  label = "region",
  text = NULL,
  colour = "colour",
  palette = NULL,
  na.colour = "darkgrey",
  na.alpha = 1,
  show.legend = TRUE,
  options.legend = NULL,
  ...
)

Arguments

.data	A data.frame to use for plot aesthetics. Must include a column called "region" corresponding to regions.
atlas	Either a string with the name of a 3d atlas to use.
surface	String. Which surface to plot. Either "pial","white", or "inflated"[default]
hemisphere	String. Hemisphere to plot. Either "left" or "right"[default], can also be "subcort".
label	String. Quoted name of column in atlas/data that should be used to name traces
text	String. Quoted name of column in atlas/data that should be added as extra information in the hover text.
colour	String. Quoted name of column from which colour should be supplied
palette	String. Vector of colour names or HEX colours. Can also be a named numeric vector, with colours as names, and breakpoint for that colour as the value
na.colour	String. Either name, hex of RGB for colour of NA in colour.
na.alpha	Numeric. A number between 0 and 1 to control transparency of NA-regions.
show.legend	Logical. Toggle legend if colour is numeric.
options.legend	list of layout changes to colour bar
...	additional arguments to add_trace Available surfaces: 'inflated:' Fully inflated surface 'semi-inflated:' Semi-inflated surface 'white:' white matter surface

Details

This package contains data from various brain parcellations, with convenient functions to inspect the results directly on a brain-plot wither with plotly in 3d meshes.

Value

a plotly tri-surface mesh plot
