trialwise: trialwise

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

trialwise

Description

Generate one regressor per trial (plus an optional grand-mean column) by delegating everything to hrf().

Usage

trialwise(
  basis = "spmg1",
  lag = 0,
  nbasis = 1,
  add_sum = FALSE,
  label = "trial"
)

Arguments

basis, lag, nbasis	Passed straight to hrf().
add_sum	If TRUE, append a column that is the average of all trialwise columns (useful as a conventional main effect).
label	Term label / prefix for the generated columns.

Details

Use it only on the RHS of an event-model formula:

onset ~ trialwise(basis = "spmg1", add_sum = TRUE)
