Plot a functional connectivity matrix

Render a square correlation or phase-locking matrix as a heatmap using the dynR diverging palette (deep indigo -> periwinkle -> brick red), centred at zero. Matches the colour scheme used in the dynR vignettes and pkgdown site.

Usage

plot_fc(fc_matrix, title = "Functional connectivity", limits = c(-1, 1))

Arguments

fc_matrix

Numeric matrix [N x N]. Pearson correlations or phase-locking values.

title

Character. Plot title. Default "Functional connectivity".

limits

Numeric vector c(lo, hi). Colour scale limits. Default c(-1, 1).

Value

A ggplot object.

Examples

data(fc, package = "dynR")
plot_fc(fc[1:20, 1:20])
