Examples

pe <- PhysioExperiment(
  assays = list(raw = matrix(rnorm(1000), nrow = 100)),
  samplingRate = 100
)

# Add stimulus events
pe <- addEvents(pe, onset = c(1, 2, 3), type = "stimulus")

# Add response events
pe <- addEvents(pe, onset = c(1.5, 2.5), type = "response", value = c("hit", "hit"))
nEvents(pe)  # 5 events total
#> [1] 5
