Convenience function to add many slices in a montage along one of the 3D planes

Description

Convenience function to add many slices in a montage along one of the 3D planes

Usage

montage(
  plane = NULL,
  n = 12,
  min = 0.1,
  max = 0.9,
  min_coord = NULL,
  max_coord = NULL
)

Arguments

plane	a character string specifying the 3D plane: "sagittal", "axial", "coronal", "x", "y", or "z"
n	number of slices to add in this plane. Default: 12
min	the lowest quantile to be included in the montage (between 0 and 1). Default: 0.1
max	the highest quantile to be included in the montage (between 0 and 1). Default: 0.9
min_coord	the lowest spatial position (in image coordinate space) to be included in the montage.
max_coord	the highest spatial position (in image coordinate space) to be included in the montage.

Details

This can be used with slices to make a quick montage, such as ⁠slices(montage("axial", 10)⁠.

Also note that use of standardized coordinates (in quantiles, using min and max) is mutually exclusive with the the image coordinate specifications min_coord and max_coord.

Value

a character string containing the slice positions along the requested axis

Examples

  t1 <- system.file("extdata", "mni_template_2009c_2mm.nii.gz", package = "ggbrain")
  gg_obj <- ggbrain() +
    images(c(underlay = t1)) +
    slices(montage("sagittal", 15))
