On this page

Opens Freeview to take snapshots and compiles them into a plot

Usage

qdecr_snap(
  vw,
  stack = NULL,
  type = c("coef", "se", "t", "p"),
  ext = ".tiff",
  zoom = 1,
  compose = TRUE,
  plot_brain = TRUE,
  save_plot = TRUE,
  sig = TRUE,
  ...
)

Arguments

vw: The output object of a qdecr call (e.g. qdecr_fastlm)
stack: Either a numeric or a string for your variable (use stacks(vw))
type: The type of map to plot (currently for OLS). Default is coef, others are se, t and p
ext: Extension of the image files that will be stored on disk
zoom: Float that determines how far the brains are zoomed in
compose: Logical; if TRUE, a single compiled image will be made (requires Magick++)
plot_brain: Logical; if TRUE, returns a graphical device with the composed images
save_plot: Logical; if TRUE, saves the composed image
sig: Logical; if TRUE, only the significant clusters are shown
...: any arguments that freeview (on command line) normally takes for manipulating surface files

Details

This function directly calls Freeview and generates files (by default .tiff) and additionally composes the images and plots them. Magick++ is required for the composing step (see www.qdecr.com).
