design_map.baseline_model: Heatmap visualization of the baseline_model design matrix

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

Heatmap visualization of the baseline_model design matrix

Description

Produces a heatmap of all columns in the design matrix for a baseline_model object, with rows corresponding to scans and columns corresponding to regressors. By default, it draws horizontal lines separating runs (blocks), and rotates the column labels diagonally.

Usage

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

Arguments

x	A baseline_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, used as the midpoint in ggplot2::scale_fill_gradient2() to center the color scale (for example at 0).
fill_limits	Numeric vector of length 2 or NULL; passed to the fill scale limits argument. Can clip or expand the color range.
...	Additional arguments forwarded to ggplot2::geom_tile().

Value

A ggplot2 plot object.
