fmrihrf 0.2.0
New Features
- New
hrf_boxcar() function for simple boxcar (step
function) HRFs with optional normalization.
- New
hrf_weighted() function for arbitrary
weighted-window HRFs with constant or linear interpolation.
regressor() now accepts a list of HRF objects for
trial-varying HRF designs.- New
plot.Reg() method for visualizing regressor
objects.
- New
plot_regressors() for comparing multiple regressors
on one plot (ggplot2 or base R).
- New
plot_hrfs() for comparing multiple HRF shapes.
- New
print.HRF() method for concise HRF summaries.
Improvements
- Revised hemodynamic response and regressor vignettes.
- Expanded test suite for new HRF types and trial-varying
regressors.
Bug Fixes
- Fixed critical bug in
as_hrf() where parameters stored
in the params attribute were never used at evaluation time.
The fix creates a closure that properly captures and applies parameters
during evaluation.
