event_basis: Create an event set from a ParametricBasis object

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

Create an event set from a ParametricBasis object

Description

This function generates an event set object from a given basis object of type ParametricBasis. It is useful for creating event sequences based on basis functions for fMRI data analyses.

Usage

event_basis(
  basis,
  onsets,
  blockids = 1,
  durations = NULL,
  subset = rep(TRUE, length(onsets))
)

Arguments

basis	A ParametricBasis object containing the basis functions
onsets	A numeric vector of onsets for each event in the sequence
blockids	A numeric vector of block identifiers for each event in the sequence (default: 1)
durations	A numeric vector of durations for each event in the sequence (default: NULL)
subset	A logical vector indicating a subset of the basis object to use (default: TRUE for all elements)

Value

An object representing the event set based on the basis functions, with class "event_basis" and "event_seq"

Examples

# Create a ParametricBasis object
basis <- ParametricBasis("Gamma", shape = 6, rate = 0.9)
onsets <- seq(0, 20, length.out = 21)
blockids <- rep(1, length(onsets))

# Generate an event_basis object
ebasis <- event_basis(basis, onsets, blockids)
