single_trial_regressor: single_trial_regressor

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

single_trial_regressor

Description

construct a regressor object that has a single onset

Usage

single_trial_regressor(
  onsets,
  hrf = HRF_SPMG1,
  duration = 0,
  amplitude = 1,
  span = 24
)

Arguments

onsets	the event onset in seconds, must be of length 1.
hrf	a hemodynamic response function, e.g. HRF_SPMG1
duration	duration of the event (default is 0)
amplitude	scaling vector (default is 1)
span	the temporal window of the impulse response function (default is 24)

Value

an S3 list of type single_trial_regressor

Examples

reg <- single_trial_regressor(c(10), HRF_SPMG1)
pred <- evaluate(reg, seq(0,100,by=2))
nbasis(reg) == 1
