Quick Start
library(fmrireg)
# Load a benchmark dataset
bm <- load_benchmark_dataset("BM_Canonical_HighSNR")
# Create an event model
events <- bm$core_data$event_table
sframe <- sampling_frame(blocklens = bm$core_data$run_length, TR = bm$core_data$TR)
emod <- event_model(onset ~ hrf(condition), data = events,
block = ~run, sampling_frame = sframe)
# Fit the model
fit <- fmri_lm(emod, dataset = bm$core_data)Documentation

Performance Configuration
The internal C++ routines use RcppParallel. You can control the number of threads by setting the R option fmrireg.num_threads or the environment variable FMRIREG_NUM_THREADS before loading the package. If either is set, fmrireg calls RcppParallel::setThreadOptions() when it loads.
Development Status
fmrireg is currently in active development. While the core functionality is stable, the API may change as we continue to improve the package. Please file issues for bugs or feature requests.
