Plot a montage of axial (or any-plane) slices using facetting

This avoids extra dependencies by using a single ggplot with facets and a shared colorbar. Supply a list of slice objects or a volume + indices.

Usage

plot_montage(
  x,
  zlevels = NULL,
  along = 3L,
  cmap = "grays",
  range = c("robust", "data"),
  probs = c(0.02, 0.98),
  ncol = 6L,
  downsample = 1L,
  title = NULL,
  subtitle = NULL,
  caption = NULL
)

Arguments

x: Either a 3D volume object accepted by `slice()` or a list of slices.
zlevels: Integer indices of slices to plot (if `x` is a volume).
along: Axis along which to slice (1 = sagittal, 2 = coronal, 3 = axial).
cmap: Palette name or vector (see [resolve_cmap()]).
range: "robust" (quantile-based) or "data" (min/max).
probs: Quantiles for `range="robust"`.
ncol: Number of columns in the facet layout.
downsample: Integer decimation for speed.
title, subtitle, caption: Optional ggplot labels.
