In bbuchsbaum/fmrireg: R package for the anlysis of fmri data

Heatmap visualization of the combined fmri_model design matrix

Description

Produces a single heatmap of all columns in the design matrix from an fmri_model object, which merges both the event_model and baseline_model regressors. Rows are scans; columns are regressors. Optionally draws horizontal lines between blocks (runs), and rotates x‐axis labels diagonally for readability.

Usage

design_map.fmri_model(
  x,
  block_separators = TRUE,
  rotate_x_text = TRUE,
  fill_midpoint = NULL,
  fill_limits = NULL,
  ...
)

Arguments

x	An fmri_model object.
block_separators	Logical; if TRUE, draw white horizontal lines between blocks.
rotate_x_text	Logical; if TRUE, rotate x-axis labels by 45 degrees.
fill_midpoint	Numeric or NULL; if not NULL, passed to scale_fill_gradient2 to center the color scale (e.g. fill_midpoint=0).
fill_limits	Numeric vector of length 2 or NULL; passed to the fill scale limits= argument. This can clip or expand the color range.
...	Additional arguments passed to geom_tile.

Value

A ggplot2 plot object.
