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
#> [1] TRUE
