brainGraph (version 3.1.1)

plot_volumetric: Plot group distributions of volumetric measures for a given brain region

Description

This function takes a “tidied” dataset of cortical volumetric measures (thickness, volume, LGI, etc.) and plots a histogram or violin plot for 1 or more groups, and of 1 or more brain regions.

Usage

plot_volumetric(
  dat,
  regions,
  type = c("violin", "histogram"),
  all.vals = TRUE,
  modality = c("thickness", "volume", "lgi", "area")
)

Value

A trellis or ggplot object

Arguments

dat

A data table of volumetric data; needs columns for 'Group', 'region', and 'value'

regions

A vector of character strings or integers of the brain region(s) to plot; if integer, the region(s) is/are chosen from the input data table based on the index

type

A character string indicating the plot type; either 'histogram' or 'violin'

all.vals

A logical indicating whether or not to plot horizontal lines for all observations (only valid for 'violin' plots) (default: TRUE)

modality

A character string indicating the type of volumetric measure ('thickness', 'volume', 'lgi', or 'area')
