Plot topographic map animation

Creates a series of topographic maps across time.

Usage

plotTopomapSeries(x, times, ...)

Arguments

x

A PhysioExperiment object with electrode positions.

times

Numeric vector of time points to plot.

...

Additional arguments passed to plotTopomap(), including interpolation and the spherical-spline controls.

Value

A list of ggplot objects.

Details

The interpolation method and controls are forwarded unchanged to plotTopomap().

Examples

# \donttest{
pe <- PhysioExperiment(
  assays = list(raw = matrix(rnorm(400), nrow = 100, ncol = 4)),
  colData = S4Vectors::DataFrame(label = c("Fz", "Cz", "Pz", "Oz")),
  samplingRate = 100
)
pe <- applyMontage(pe, "10-20")

# Create topomaps at multiple time points
plots <- plotTopomapSeries(pe, times = c(0.1, 0.2, 0.3, 0.4))
