reposition_brain: Reposition brain slices

Description

Function for repositioning pre-joined atlas data (i.e. data and atlas already joined to a single data frame). This makes it possible for users to reposition the geometry data for the atlas for control over final plot layout. For even more detailed control over the positioning, the "hemi" and "view" columns should be converted into factors and ordered by wanted order of appearance.

Usage

reposition_brain(
  data,
  position = "horizontal",
  nrow = NULL,
  ncol = NULL,
  views = NULL
)

Value

sf-data.frame with re-positioned slices

Arguments

data

sf-data.frame of joined brain atlas and data

position

Position formula for slices. For cortical atlases, use formulas like `hemi ~ view`. For subcortical/tract atlases, use "horizontal", "vertical", or `type ~ .` for type-based layout.

nrow

Number of rows for grid layout (subcortical/tract only)

ncol

Number of columns for grid layout (subcortical/tract only)

views

Character vector specifying view order (subcortical/tract only)

Examples

reposition_brain(dk(), hemi ~ view)
reposition_brain(dk(), view ~ hemi)
reposition_brain(dk(), hemi + view ~ .)
reposition_brain(dk(), . ~ hemi + view)

# \donttest{
reposition_brain(aseg(), nrow = 2)
reposition_brain(aseg(), views = c("sagittal", "axial_3"))
