image(
  x,
  BGimg = NULL,
  limits = 0,
  nrow = NULL,
  index = NULL,
  crop = TRUE,
  col = gray(0:64/64),
  colpos = pbj:::redyellow(64),
  colneg = pbj:::bluecyan(64),
  plane = c("axial", "coronal", "sagittal"),
  title = "",
  axes = FALSE,
  lo = TRUE,
  ...
)

Arguments

x	the Nifti object to display images of
BGimg	background image to use.
limits	A lower (and optionally upper length 2 vector) limits to apply to the image, defaults to 0
