Compute vertex-wise differences between two maps

Source: R/plot_helpers.R
vw_diff.Rd

Calculates the absolute difference (a - b) between two cortical surface maps for both the left and right hemispheres. Prints statistical summaries of the difference distribution.

Usage

vw_diff(
  lh_a = NULL,
  lh_b = NULL,
  rh_a = NULL,
  rh_b = NULL,
  label_a = "a",
  label_b = "b"
)

Arguments

lh_a, lh_b

Left hemisphere data maps (numeric vectors or file paths) to contrast.

rh_a, rh_b

Right hemisphere data maps (numeric vectors or file paths) to contrast.

label_a

Character string representing the name of the first map (a).

label_b

Character string representing the name of the second map (b).

Value

A named list containing lh and rh numeric vectors representing the calculated differences (a - b).
