Plot a signal channel

Generates a simple line plot for the selected channel and sample from the default assay. Supports both 2D (time x channel) and 3D (time x channel x sample) assay arrays.

Usage

plotSignal(x, channel = 1L, sample = 1L, assay_name = NULL)

Arguments

x

A PhysioExperiment object.

channel

Integer index for the channel.

sample

Integer index for the sample (only used for 3D arrays).

assay_name

Optional assay name. If NULL, uses the default assay.

Value

A ggplot object.
