Plot an HRF Object

Creates a visualization of an HRF object. For single-basis HRFs, shows the response curve with peak annotation. For multi-basis HRFs (e.g., HRF_SPMG3), shows all basis functions on the same plot.

Usage

# S3 method for class 'HRF'
plot(x, time = NULL, normalize = FALSE, show_peak = TRUE, ...)

Arguments

x

An HRF object

time

Numeric vector of time points. If NULL (default), uses seq(0, span, by = 0.1) where span is the HRF's span attribute.

normalize

Logical; if TRUE, normalize responses to peak at 1. Default is FALSE.

show_peak

Logical; if TRUE (default for single-basis HRFs), annotate the peak time and amplitude on the plot.

...

Additional arguments passed to underlying plot functions.

Value

Invisibly returns a data frame with the time and response values (useful for further customization).

Examples

# Plot single-basis HRF
plot(HRF_SPMG1)


# Plot multi-basis HRF
plot(HRF_SPMG3)


# Plot with normalization
plot(HRF_GAMMA, normalize = TRUE)


# Custom time range
plot(HRF_SPMG1, time = seq(0, 30, by = 0.5))
