plot_contrasts.event_model: plot_contrasts.event_model

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

plot_contrasts.event_model

Description

Produces a heatmap of all contrasts defined for an event_model. Rows = each contrast (or column of an F-contrast), columns = each regressor in the full design matrix, and the fill color = the contrast weight.

Usage

## S3 method for class 'event_model'
plot_contrasts(
  x,
  absolute_limits = FALSE,
  rotate_x_text = TRUE,
  scale_mode = c("auto", "diverging", "one_sided"),
  coord_fixed = TRUE,
  ...
)

Arguments

x	An event_model with (lazily) defined contrasts.
absolute_limits	Logical; if TRUE, the color scale is fixed at (-1,1). If FALSE, the range is set to (min, max) of the weights.
rotate_x_text	Logical; if TRUE, rotate x-axis labels for readability.
scale_mode	Character; 'auto', 'diverging', or 'one_sided' color scaling.
coord_fixed	Logical; if TRUE, use fixed aspect ratio.
...	Further arguments passed to geom_tile, e.g. color="grey80".

Value

A ggplot2 object (a heatmap).
